Australia is one of the countries that have strictly defined laws in respect of ensuring workplace safety. One of the segments included in preserving worker’s health and safety at the work site is the so called PAT (Portable Appliance Testing). PAT is in fact inspecting and checking the functional electrical appliances included in the work operations for potential defects that might be a further cause of an unwanted outcome of their operation. This is done by visual examination of the equipment and also by using special test and tag equipment. The testing equipment is usually used by electricians who test the equipment and on the base of the test/s determine whether certain electrical appliance needs maintenance, repair or replacement.
Now that you know why do you need to invest in quality test & tag equipment, the next step is to learn more about the different types of test and tag testing devices in order to make the best choice for the needs of your business. But before that, let’s take a look at the most factors that you need to consider before you start your quest for test & tag equipment. In brief, the initial step in selecting the most appropriate testing devices include:
- Determining your budget;
- Defining the actual purpose of use of the test and tag equipment;
- Determining the average number of tests that will be performed on your work site.
After you determine the aforementioned factors, the next step is to choose the right type of PAT testers. Generally speaking, this type of testers are classified into several categories: basic pass/fail testers, entry level testers, mid range testers and professional testers.
Some of the most important factors that come into play when choosing the most suitable test & tag equipment for your work site include: ability to measure power (either in kilowats (kW) or volt-ampers (VA)); option for recording and storing data (there are PAT testers that allow storing of around 40,000 results); ability to test trip time ans trip current on RCD’s and so on.
The most common types of test that are performed with the use of test & tag equipment include testings for: earth resistance, insulation resistance; earth leakage; RCD trip time; battery operation; current consumption and so on. Testing the electrical appliances and measuring the parameters for the above-mentioned factors is important for the general worker’s safety at the work site.
