The AC High Voltage Tester is commonly employed to assess the efficiency of electrical equipment. In order to meet the required standards, quality, and reliability, the manufacturer conducts primary high voltage testing as a part of the type and routine tests during production. These tests encompass various measurements such as partial discharge, switching impulse, lightning and switching resistance, as well as insulation resistance.
While the field testers used for maintenance purposes have a significantly lower range, this particular AC High Voltage Tester utilizes generators that operate within the capacity range of electricity up to 100 KV and beyond. Its purpose is to evaluate the insulation between primary and secondary, as well as between primary and earth, and secondary and earth.
How is High Voltage Testing Conducted?
High voltage testing is commonly performed during installation tests or routine maintenance. One of the most frequently used tests is the withstand voltage test, which assesses the transformer’s dielectric strength to determine if it is sufficient for service or as part of maintenance programs to ensure that the equipment can withstand high voltages while in use. Typically, the transformer’s mains and secondary or secondary and ground are subjected to an overvoltage for a duration of 60 seconds. If the measured current is below the maximum permitted leakage current and does not cause insulation failure, the high voltage testing is considered successful, indicating that the product is safe to use under normal operating conditions. The SMC Raptor System now offers this type of testing.
Advantages of AC High Voltage Testing
Businesses in the high voltage technology sector are required to regularly conduct routine inspections to ensure the integrity, condition, and safety of their equipment. Authorized personnel should perform regular maintenance to assess the current state of the equipment. Equipment testing is crucial in determining the overall integrity of the machines. These routine inspections are carried out to prevent equipment or machine failures that could result in significant productivity losses. Some of the leading AC High Voltage Tester Manufacturers in India recommend periodic equipment checks.
These machine assessments can also help determine the value of recently purchased equipment before its installation. Several manufacturing sectors test the insulation of their equipment using high voltage before selling it to customers.
The reliability and quality of the machines have a significant impact on the benefits of using high voltage insulation testing. The testing methods provide reliable and effective insulation for any electrical equipment, as the machines undergo multiple stages of testing to ensure flawless operation and suitability for functioning.
