 &Nbsp; 1. The meaning of high voltage test

High voltage electrical test equipment refers to the continuous or intermittent testing of the operating performance of power equipment using corresponding means. The information obtained from the test is analyzed in conjunction with the specified operating standards of electrical equipment, and hidden equipment hazards are identified and timely measures are taken to eliminate them, in order to prevent potential problems and ensure the long-term stable operation of the power grid

2. Process of high-voltage test equipment testing

Step 1: Select a matching power supply suitable for the test equipment and a configuration that meets the requirements of software system operation Step 2: Initialize measurement parameters and record various types of data Step 3: Diagnose potential faults of equipment based on data information and estimate fault trends Step 4: Evaluate the health status of the testing equipment Step 5: Develop preliminary test results Step 6: Determine the main indicators and factors that affect equipment operation

3. Common high-voltage tests and methods for high-voltage testing equipment

Based on the properties of the power supply used, common types of high-voltage tests include DC withstand voltage test, AC withstand voltage test, high-frequency oscillation withstand voltage test, and leakage current:

1) DC withstand voltage test

DC withstand voltage test is destructive, and electrical equipment may be affected by it. In order to detect the voltage peak that the equipment can withstand, the test voltage is very high. This helps to timely detect electrical equipment with local insulation defects, intercept equipment with poor insulation performance in the power system, and ensure stable operation of the power grid

2) AC withstand voltage test

This is a direct and effective method for detecting the insulation strength of equipment, and is an important part of preventive testing, which can detect concentrated and serious problems in the equipment as soon as possible.

3) High frequency oscillation wave withstand voltage test

High frequency oscillation wave withstand voltage test has a good effect on discovering mechanical damage and water tree type insulation defects.

4) Leakage current test

Leakage current test is a method of determining the insulation status of equipment by measuring the leakage current value between the insulation of equipment using DC voltage and ground, based on data.
