Testers and Meters For El. Installations
(838)Electrical installation tester – an important tool for every electrician
We interact with electrical installations every day when we use home appliances like washing machines or dryers. However, a large subgroup of electrical installations are specialised systems powering factories and production floors. Depending on the intended use of an electrical installation, it may have to be checked regularly. This is where testers and meters come in. You will find a large selection of electrical installation testers at TME. Those devices let you monitor a number of parameters, including insulation resistance, resistance to earth, electric energy quality, and voltage in a system.
Electrical installation testers – what are they used for?
Over time, various components of an electrical installation – cables, switches in dashboards or fuse boxes – can break down. This can be caused by a temporary overvoltage or the components simply wearing down. That’s why you should regularly check various parameters of your electrical installation. In production facilities and factories, those tests are performed regularly because installations are much more likely to break down there. This is caused, among other factors, by environmental conditions or exposure to hazardous substances like acids and solvents.
Meters and testers can also get damaged. That’s why electrical installation testing devices available at TME have robust housings with IP ratings up to IP67.
Electrical installation testers – what are their types and which parameters can you measure them with?
Thanks to technological advances, all measurement devices are now much smaller, more ergonomic and convenient. They can also measure more parameters. Modern electrical installation testers are multifunctional devices. They let you analyse data on-site or send it using a USB cable or Bluetooth connection to your smartphone or PC.
Voltage and continuity testers
The most basic voltage tester is just a regular screwdriver connected to a diode. As you can probably tell, that’s not the most precise device – all you can do with it is check whether there is voltage in a circuit at all. And the imprecise tip that is only useful in some situations doesn’t make things easier, either.
Modern electrical installation testers let you perform many operations, including voltage tests, conductivity checks, and phase sequence checks. Data is shown on large diode displays that can also be LED- or OLED-based. What’s more, good readings are indicated with a sound, a display diode lighting up, and – in the latest models – with vibration.
Insulation resistance meters
Insulation protects users from electric shock, so checking it is crucial. Modern resistance meters have a range from 0 do 20GΩ, and measured data is shown directly onscreen. What’s important is that many insulation testers can save and process data. This, in turn, lets you analyse and look for trends. This is especially vital in industrial installations because cables have to bear much heavier loads there. TME’s offer also includes devices that let you measure multicore cables, speeding up the whole testing procedure.
RCD testers
RCDs (residual-current devices) break the flow of electrical current in a circuit when an earth current that is too high is detected. RCDs are one type of safety elements protecting entire installations. RCD testers detect incorrect wire connections, measure resistance to earth, and test all types of RCDs (AC, regular, selective).
A wide selection of electrical installation testers available at TME
Modern electrical installation testers need to be highly reliable, versatile, and easy to use. Technological progress has made it possible to store and thoroughly process many measurement results. TME’s offer includes a wide selection of devices that let you check the condition of your electrical installations – from phase sequence indicators to the more specialised power quality analysers. All devices are from renowned manufacturers and comply with the EN61010 600V CAT IV and EN61010 690V CAT III European standards.
