Surge Power Board Protection 101

We have such a large number of gadgets today and they nearly all have sensitive electronic components particularly for our entertainment and computing equipment. We are told that we need to protect that equipment for Electrical surges from our mains power supply. The easiest and most convenient way is to buy a Surge Protected Power Board … However, not all surge protectors are alike, and some even put your gadgets at risk. So what is the Difference between a Surge Protected Power Board and a plain power board? Firstly, not every power board is a surge protected power board. It may sound basic, but it’s a fundamental piece of knowledge you’ll need. While a power board just splits your outlet into multiple ports, a surge protector is designed to protect your computer, TV, and other electronics against power surges and any interference or noise on your power line. Power surges may not be an everyday event, but they’re common enough that they can damage your equipment. What to look for: Look for a Label that states its Surge Protected and also look for a led light on the board which indicates that it the Surge Protection is working when the board is plugged in. This will act as a check if there has been major surge event in the Mains power supply.  If the led light goes off the Surge protection may be blown and it will indicate that it is no longer working even though the board is still supplying power to connected devices. Buy one with right number of outlets they come in typically 6,8,12 outlets (this avoids connecting many boards together compromising your protection and potentially overloading power to appliances from the power-point.) DO NOT buy single a single outlet device they are usually cheap and provide poor protection your expensive appliances. Do not connect High current appliances to a Surge Protected power Board they are designed for sensitive Low Power Devices (Tvs, DVD Players, Game Consoles, Hi-fi, Computer Devices etc) for example, do not connect Kitchen appliances, Air Conditioners, Tools and Workshop equipment to a Surge Protected Power Board Always check the design specifications

  • Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200joules. For better protection, look for a rating of 600 joules or more.
  • Clamping voltage. The clamping voltage is the voltage that will trigger the surge protector—or essentially when the surge protector wakes up and starts absorbing energy. Look for something around 400 V or less. Lower is better here. Finally, see if response time is listed in the product details—it’s good to know, and lower is better
  •  Response time – Surge protectors don’t kick in immediately; there is a very slight delay as they respond to the power surge. A longer response time tells you that your computer (or other equipment) will be exposed to the surge for a greater amount of time. Look for a surge protector that responds in less than 20 nanoseconds.
  • As mentioned before, It is best to look for a Surge protected board with an indicator light that tells you if the protection components are functioning

Importantly: Make sure you’re informed before you buy, and read the back of the box or the product details before you buy anything. You don’t want to invest in a surge protector only to find out that it’s far too weak to protect your devices, or it’s a surge protector in name only. Remember,  the most expensive is not always the best. The best thing to do is figure out what you need to protect and buy accordingly.

What you need to do to manage Electrical Risk in the Workplace

Managing electrical equipment and installations

A business needs to ensure that:

  • power circuits are protected by appropriately rated fuses or circuit breakers
  • electrical leads are not arranged so that they are easily damaged, run across floors or doorways, or over sharp edges
  • only leads and tools designed for wet or damp conditions are used in those conditions
  • circuits where portable equipment may be connected are protected by RCDs
  • if any current protective device (RCD or circuit breaker) is triggered, the system is not re-energised until the reason has been identified by a competent person
  • equipment identified as unsafe is disconnected or isolated and labelled as unsafe and not reconnected until it is repaired and tested as being safe
  • regular visual inspections and testing of electrical equipment, including RCDs, occurs. The nature and frequency of inspection and testing will vary depending on the electrical risks.

So what is tested and what are we looking for when doing a Test and Tag regime?

Many of our clients organise regular test and tagging services simply because it is easier and safer.

A regular program of testing and tagging comprises of: (standard 10/15Amp 3 wire cabled appliance and plugged multi phase equipment)

A visual check to ensure the integrity of the Electrical cord and Appliance construction

  • The Technician looks for Cuts and breaks in appliance and power cables may present as an  electrical hazard.
  • An inspection of the integrity of the appliance housing looking for cracks and holes which may expose personnel to an electrical hazard.

A series of electrical tests are then conducted to detect the unobservable faults not found by the visual inspection process, and forms an integral part of the inspection/testing process.

The equipment is turned off to allow the technician access to the appliance plug. All tests are performed by disconnecting the appliance from the building power and connecting the plug to an insulation tester or a Portable Appliance Test-set built for the purpose of performing the tests automatically and uniformly. These Tests are:

  1. Earthing continuity test: (specifically for metal shrouded appliances) to ensure there is adequate connection between the earth pin on the plug of the appliance and the metal cover shrouding the appliance.
  2. Insulation resistance test: to ensure that no path exists with the appliance/lead for electrical current to transit from the active wires to earth.
  3. Continuity Loop test: to make the sure that the active circuit which powers the appliance has a good solid connection and in no way presents as an electrical hazard.
  4. Polarity Test: (only for items which distribute power: leads, power-boards, adapters etc) to ensure that the wires of an extension cord/power board appear the same order of connection at the plug as the do at the socket end.

Other Equipment Tests Include:

 RCD test to test the tripping time of a RCD to ensure your safety switch or RCD does work properly and switches off in a fault situation quick enough to save personnel from Harm.

3Phase Test: usually high powered workshop and building site equipment with multiple active wire connections (tests performed on 3phase test are similar to that of standard appliance tests outlined above)

Emergency Exit sign test: Tests the ability for an emergency exit sign to stay on when power is off 90 minutes is the expected time, if it fails to reach the expected time then the circuitry/ battery will be in need repair or replacement .

That is it, in a very basic overview if you need to know more please either contact us or contact Safe-Work SA (South Australia) http://www.safework.sa.gov.au/  1300 365 255 or The Workplace Safety Authority in your local area.

Buyers Guide To Surge Power Boards

How do surge protected power boards work ?
At first glance a surge protected power board operates like any other Power Board. It shows its ability at that moment when too much voltage gets passed along the transmission line , the surge protected board lets only a ‘safe’ amount through to the connected equipment. The rest it channels into the electrical outlet’s ‘earth’ and safely dissipated into the ground.
When a surge occurs at a certain level above normal voltage, a component built into the surge protected power board becomes conductive and starts to carry the excess electric current back down through the ground wire, so the damaging high voltage doesn’t reach connected equipment. Once the surge ends, that protective component resumes its ‘dormant’ stage of being non-conductive. It’s a bit like an electrical version of a pressure valve.
Australian domestic wiring is designed for a standard voltage of 230–240 volts. If the voltage goes too far above that, it can damage electronic equipment, which usually has many sensitive components. If excess voltage lasts for a very brief time (1–2 nanoseconds) it’s called a spike. If it lasts longer it’s called a surge. Even though a spike or surge can be so brief their duration is measured in nanoseconds, they can still cause damage to sensitive components. It is vitally important to protect sensitive business equipment, Computers, printers, photocopiers etc these items of equipment are sensitive to Surges in voltage.

So what sort of a Surge Protected Board should you Buy ? Here are the specifications you should consider…Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
Response time – Surge protectors don’t kick in immediately; there is a very slight delay as they respond to the power surge. A longer response time tells you that your computer (or other equipment) will be exposed to the surge for a greater amount of time. Look for a surge protector that responds in less than Ten nanoseconds.
It is best to look for a Surge protected board with an indicator light that tells you if the protection components are functioning. Eventually the protection component will burn out after continual power surges, but the board will still function as a power connection. Without an indicator light, you have no way of knowing if your protector is still functioning properly.
Other important features may include ?
Building wiring status indicator: Detects potentially dangerous wiring problems in the wall outlet.
Circuit breaker: Protects the surge board from overload by connected devices drawing too much current.
EMI noise filtration: This reduces or eliminates line noise (electrical interference).
Other connections: Surge protected sockets for coaxial cable, modem or Ethernet network, all of which can also conduct high voltage that can damage connected devices.
Outlet spacing: Allows more room for one or more devices that use a transformer block.
Sockets: Check the number of mains power sockets available, usually from four to eight.

Fire Hazards heaters, clothes dryers & electric blankets

Each winter heaters, electric blankets and tumble dryers cause a large number of house fires in Australia. Have you checked and kept up your maintenance by simply following these valuable tips

Removing hazards and safe use of heaters

  • Never leave heaters unattended. If a fire starts it could spread through your home before you are able to respond.
  • Keep flammable materials at least a metre away from the heater. The majority of house fires are caused by people hanging clothes or towels to dry on or in front of the heater. Clothes, upholstery, curtains and other material that could catch fire should be kept more than a meter from any heater at all times.
  • Make sure portable heaters are secured upright and not left in locations where people or pets could knock them over.
  • Avoid using portable heaters on table tops unless they are secure and designed for that purpose. There is a risk of heat damage to the table top and if it falls off it could damage the heater and start a fire.

Electric heater safety tips

  • Don’t plug electric heaters into powerboards, double adaptors or extension cords with other appliances. Heaters consume large amounts of power and may overload the supply and cause a fire.
  • Before using an electric heater check the condition of the appliance and power cords for obvious damage. If there is damage contact an electrician or the service technician to fix it.

Gas heater safety and correct use

  • Never use gas heaters designed or marked for outdoor use inside. They are a fire risk and can also release toxic gases which can accumulate inside and potentially harm you. Using LPG cylinders indoors to provide fuel for unflued heaters or other gas appliances is dangerous and is not recommended.
  • Unflued heaters must not be used in bedrooms, bathrooms or small rooms that have no permanent ventilation. Toxic gases can build up inside and potentially harm you.
  • Never use your gas oven or stove as a room heater.
  • Always check your gas heater is working correctly. Signs of problems with gas heaters may include difficulty when lighting, yellow flames, unusual smells or noisy or inoperable fans.
  • Regularly service your gas heater according to the manufacturer’s instructions. Always use a licensed gas fitter for this task.

Clothes dryer safety

  • Ensure that the lint filter is cleaned regularly. Lint that has built up can catch fire.
  • Follow manufacturer’s instructions and only place suitable materials into the clothes dryer.

Electric blanket safety

Do you really need them they can be dangerous and not certainly not recommended for use with children (eg Bedwetting) If you really need to use one then every year take it out and give it a thorough check.

  • Electric blankets should be rolled when stored away. Folding an electric blanket can damage element wires within the blanket
  • When using a blanket for the first time after storage, lay it flat on the bed and check for hot spots as it heats up. Only add sheets once you are sure the blanket will operate safely at a maximum temperature.
  • Electric blankets that are not properly maintained can cause fires.
  • Avoid using double adaptors or power boards wherever possible.
  • Older electric blankets might be damaged and may not have the safety features of modern blankets, so consider replacing them.

Home Fire Safety Electrical

In Australia hundreds of fires are caused by potential electrical hazards found in the home apart from fitting a smoke alarm would it not be best that you can reduce these hazards in the first place!

  • Replace or repair damaged or loose electrical cords.
  • Avoid running extension cords across doorways or under carpets.
  • In homes with small children, make sure your home has tamper-resistant (TR) receptacles.
  • Consider having additional circuits or outlets added by a qualified electrician so you do not have to use extension cords.
  • Follow the manufacturer’s instructions for plugging an appliance into a receptacle outlet.
  • Avoid overloading outlets. Plug only one high-wattage appliance into each receptacle outlet at a time.
  • If outlets or switches feel warm, frequent problems with blowing fuses or tripping circuits, or flickering or dimming lights, call a qualified electrician.
  • Place lamps on level surfaces, away from things that can burn and use bulbs that match the lamp’s recommended wattage.
  • Make sure your home has a Safety Switch or Separate RCD breakers for power outlets especially in the kitchen bathroom(s), laundry, basement, and outdoor areas.
