The basic unit of measure of electric power is the Watt. One thousand Watts are called a kilowatt. This is one of the basics you learn before going out and using your test meter at your job. Many electric meter testers are working with dangerous equipment to make sure the rest of their community has efficient and working power. So when you’re out there working with your test meter, there are a few things you can do to make sure you’re as safe as possible.
Be careful with voltage spikes
The appliances in our homes use voltages thousands of times smaller—typically just 110 to 250 volts. It does hurt when you’re shocked by an appliance, but when it comes to power lines, it can go as high as 750,000 volts. This means any voltage spike is something to be wary of. A test meter can help, but it can’t prevent a spike. The best thing you can do is to make sure your energy meter testing equipment is up to date.
Know your CAT
When testing energy meters, make sure you know the CAT you’re working with. In general, you’re working with one of four CAT: CAT I, CAT II, CAT III, and CAT IV. The best way to differentiate it is by remembering the higher the number, the more voltage and electricity flowing through it. This also matters when it comes to working with your tools. Not all equipment is meant to work with each other. What works for a CAT I likely won’t work for a CAT IV. Try to make sure your transformer testing equipment is ready for the work you’re doing. Sadly, there’s no one way to check that your equipment is ideal, but there are other ways to see that others have checked for you.
Look for the symbol
Before using your test meter, look for symbols that show the electric materials been checked. There are a few different types you can look for. For instance. The ‘CE’ typically seen on less powerful equipment. In Europe, products cannot be imported in unless it has that symbol. While it doesn’t mean it’s perfectly safe, it does mean it’s been checked for the basics. There are also symbols from independent testers such as ‘UL’, ‘CSA’ and ‘TUV’. These are the symbols of a few independent testers, meant to help reassure you the test meter you’re using is in good condition. The IEC is responsible for setting the standards these testers use, but it doesn’t mean they have to follow it to a T.
Know the danger shock numbers
Everyone knows that electric shocks are dangerous, but not everyone knows just how little you need for it to be fatal. There are some numbers to keep in mind when you’re out there working. For example, at 10mA, your arm muscles can become paralyzed and you might not be able to release your grip. At 30mA, you can no longer breath and might die. At as low as 75mA, your heart can stop immediately. The number varies based on your weight, gender, and health, but the numbers are still extremely low. Do your best to make sure you’re not among those getting shocked on the job. Contact Powermetrix today and learn more ways to be safe with your test meter
