Electrical Testing


Electrical testing is a process of inspection that covers many different areas of the electrical system, such as medical, industrial and automotive, using various testing equipment, such as a Digital Multi-Meter, CRO, Clamp Meter, Insulation tester, etc. These testing tools are used to measure different electrical parameters, such as AC/ DC voltage, current, resistance, capacitance, frequency, continuity, insulation, etc. In an electrical system, regular insulation resistance testing is highly recommended to avoid electrical shocks and ensure safety, which reduces downtime. It helps to check the corrosion of insulation and repair works, s vacuum cleaning, steam cleaning and rewinding can be scheduled. Excessive heat or cold, moisture, corrosive vapours, oil, vibration, aging and nicked wiring are the primary causes of insulation failure. The equipment necessary for insulation resistance tests are a megohmmeter, temperature indicator and humidity meter. The total current in the body of the insulation is the sum of capacitance charging current, absorption current and leakage or conduction current.


Electrical testing confirms that different parts of the system and its features are working correctly. It assures a safe environment free from unnecessary risks. A well planned electrical preventive maintenance schedule can reduce accidents, saves lives and minimize costly breakdowns. Impending troubles can be identified and solved before they become significant problems which may require more expensive, time-consuming solutions.


Electrical safety testing of different testing equipment is essential for safe operating standards which uses electricity. There are various agencies which have established strict requirements for electrical products. It is compulsory for an electrical product to conform to certain safety standards laid down by safety and official agencies, such as UL, CE, VDE, CSA, BSI, CCC, etc. The product must pass safety tests, such as High Voltage test Insulation Resistance test, Ground Continuity test and Leakage Current test. Here we discuss some of the common mistakes while performing electrical measurement with a Multi-Meter. We should not replace the original fuse with a locally made or cheaper one because it will change the safety standards of the Multi-Meter. It should be replaced with an authorized fuse. We should not use a bit of wire or metal to get around the fuse. We should use the appropriate Multi-Meter as per measurement work.
