The voltage tester mainly has the following functions:
1. Test insulation performance
Being able to determine whether the insulation materials of electrical equipment have aging, damage, and other issues, determine whether their insulation performance meets safety standards, promptly identify potential insulation hazards, and ensure the normal operation of equipment
2. Conduct preventive testing
Regularly conducting voltage withstand tests on electrical equipment can identify insulation faults in advance, avoid equipment shutdown accidents caused by insulation problems during operation, effectively improve the reliability and stability of equipment operation, reduce the occurrence of sudden failures, extend the service life of equipment, and reduce maintenance costs
3. Used for equipment acceptance
Before putting electrical equipment into use, voltage withstand testing is an essential acceptance step. Through this test, the quality and safety of the equipment can be ensured, preventing devices with insulation defects from entering the usage phase and ensuring the safe operation of the equipment
4. Assist in fault diagnosis
When electrical equipment malfunctions, a voltage tester can be used to detect the insulation condition of the equipment, helping technicians quickly locate the fault point and carry out targeted repairs, improving the efficiency of troubleshooting and shortening equipment downtime
5. Ensure safe operation
As one of the important means to ensure the safe operation of electrical equipment, withstand voltage testing can effectively prevent safety accidents such as electric shock and fire caused by insulation faults, protect the lives of operators and surrounding personnel, and avoid economic losses caused by insulation damage to equipment
6. Suitable for various devices and industries
In the power system, it can be used to detect the insulation performance of equipment such as transformers, switches, cables, etc; In the field of electronic devices, able to test motors, frequency converters, electrical control cabinets, etc; It also plays an important role in the production and quality control of household appliances, electronic products, and other electrical products, and is widely used in various industries involving electrical equipment such as automobiles, aviation, and railways
