Electric Circuit Testers and How They Work

Contractors, electricians, DIY handymen, and hobbyists make use of various electric circuit testers to assess different functions and parameters including voltage, resistance, continuity, and current. They come in various shapes and sizes. Here at Metrotest, we offer a wide range of electrical testers that can be used to assess electrical panels, wires, transformers, circuit breakers, and other electrical components. 

Need one for your project but not sure which one you should get? Learn more about the different electric circuit testers you can find in the shop and how you can use them in the short guide below.  

Insulation Testers

Wiring insulation ages over time, affecting its ability to protect against electrical faults. As a result, it’s a must to take the necessary steps to correct or mitigate insulation issues. One of the devices used to determine possible insulation concerns is the insulation tester. It measures resistance in motor windings and wires to determine whether there’s damaged or leaky insulation. By doing so, you can prevent issues like blown circuits and arc faults. Detecting current leakage can also protect against fatal electrical shocks or fires.

High Voltage Insulation Testers

Need to measure the insulation resistance of a high voltage device? Instead of using an ordinary tester, it’s better to use a high voltage insulation tester. This type of tester can be used on equipment that uses anywhere from 2500 volts or more. You can choose from a variety of high voltage insulation tester models, depending on the specific features you need such as data transfer and data logging. 

Power Quality Analysers

It’s virtually impossible to find flawless power quality because of equipment malfunction, excess consumption of power, service interruptions, and several other factors. Unfortunately, poor power quality can result in loss of production and damage to equipment. To minimise such risks, it’s ideal to analyze power quality on a regular basis. Utilise devices such as power quality analysers to gauge the load’s capacity to function given a certain range of electric power. The tester would show various parameters including AC power, frequency, AC voltage, peak demand, and electrical demand. 

Loop Testers

Another way to protect equipment from damages is through the use of loop testers. Essentially, a loop tester determines whether devices such as circuit breakers and fuses can protect against electrical fault. The goal is to ensure that the circuit disconnects quickly during power interruptions to eliminate the risks of overheating and fire. You can shop for a wide range of loop tester at Metrotest. For example, you can opt to buy standalone models or multi-function types. 

Cable Location Equipment

Sometimes, it’s difficult to find live and non-live wires and plumbing work in a property. Fortunately, you have the option to use specialised equipment such as a cable and pipe locator. It eliminates guesswork on the site. Regardless if the wires or pipes are buried on the ground or concealed behind a wall, wire and cable location equipment can help you get the job done right. 

Clamps and Digital Multimeters

Need to measure current? A clamp meter is the perfect tool for the job. It features jaws that clamp around a wire to gauge the magnetic field produced when current flows and a digital multimeter to measure parameters such as capacitance, voltage, resistance, and continuity buzzer. You can select from a wide range of clamp meters and digital multimeters. Choose one according to the functionalities available and the tester’s quality.

RCD testers

Most electrical accidents and fatalities can be prevented by devices such as residual current devices or RCD. These protective devices switch off power to a circuit to prevent electric shock and other accidents. To check if an RCD still works properly, you can use an RCD tester to safely trip the device. The faster the device trips, the better protection it can provide from fatal electric shocks.    

Multifunction Installation Testers

Looking for an all-in-one tester for your home o business? A multifunction tester is the best equipment to have in your toolbox. They come in handy when checking whether an installed wiring or electrical system adheres to the industry standard. Each multifunction electrical circuit tester model offers varying features. Hence, it’s best to check the device’s specification before purchasing.
