There are several methods of safety procedures that are used in the electric industry. The type of equipment used for the purpose of testing determines the level of testing. Moreover, there are several stages of an inspection and a different test is carried out at each stage. So here are some common types of electrical testing.

What is Electrical Testing and Tagging

Electrical testing and tagging are considered as one of the most popular service among all other types of electrical testing. This refers to the inspection and labelling of electrical equipment; Visual inspections, insulation resistance tests, earth continuity tests, leakage tests and more.

The type of work will depend on the particular device and the environment. A wide range of electrical equipment from computers, refrigerators, microwaves to other portable devices can be inspected. If you are looking for an electrician in your vicinity, search in with your area name. For example, you can search as ‘test and tag Melbourne’ to find out qualified and competent electricians closer to Melbourne.

There are many types of testing depending on what the task entails.

Visual Inspections

Visual inspections are carried out first in any electrical work. Most of the issues can be identified by this inspection. This includes smelling the electrics, tapping the appliances to check for sparks or reactions, pulling on leads to check for anything loose or uneven, shaking appliances and checking general safety and quality.

Earth Testing

This test checks the conductor of Class 1 appliances such as microwaves, extension leads, etc. The purpose is to ensure that the Earth is suitable on an appliance before conducting the Insulation Resistance Test.

Resistance Testing

This is a standard test that uses a specific type of voltage in order to measure the insulation resistance in Ohm’s.

Leakage Test

This test is important because leakages are one of the main causes for electrical shocks. A leak test shows any leak or evasion within the electrical current. Leaks can occur due to various reasons like faulty wiring, dampness and fraying in the wires themselves.

Portable Appliance Testing

This method of testing is done on equipment that is portable and is popular in construction industry as portable devices are widely used for construction purposes.

RCD Testing

Another essential type of electrical testing is safety switch testing. RCD stands for Residual-Current Device. Occupants in a building could be exposed to electrical shock if there is no functional RCD. It is important to have tested the RCD at least once a year by a skilled technician.

Earth Fault Loop Impedance Testing

An earth fault loop test helps to maintain the circuitry in a building. This test involves measuring of resistance in an electrical circuit. The circuit breakers are capable of detecting a fault when the resistance is low and operate correctly by shutting off the power. Electrical fires may occur if such faults are kept unmanaged. Therefore, you must make sure that your circuitry is timely maintained to avoid any damages.

This is to give you a general understanding about the common types of electrical testing so that it will help you to identify an electrical issue and take precautions until an expert arrives. Therefore, try to find a qualified and experienced electrician who is capable of handling your electrical issues effectively.
