The insulation resistance tester under ultra-high voltage power can help many power workers conduct various power tests more conveniently.
High voltage testing is a common and effective means of checking whether electrical equipment can operate normally. As a manufacturer of high-voltage testing equipment, we are committed to insulation testing, which is an important component of high-voltage testing.
The objects of high-voltage testing are very wide, including generators, GIS, power transformers, high-voltage cross-linked power cables, voltage and current transformers, etc. Currently, many power equipment accidents are caused by insulation faults, so insulation fault detection is undoubtedly the focus of current high-voltage testing of power equipment. In other words, as long as it involves the detection of power equipment, insulation testing must be carried out, especially in the following three situations, where insulation testing is considered a legal detection link.
1. Factory inspection of high-voltage electrical equipment
High voltage electrical equipment manufacturing enterprises must conduct insulation tests on all products, raw materials, etc. they produce. Only qualified raw materials can be put on the production line, and only qualified products can leave the factory. The product qualification standards shall not be lower than the relevant national standards or industry standards.
2. Insulation testing after equipment maintenance
Electrical equipment can also age after long-term use and requires regular maintenance. To ensure the normal use of the repaired equipment, insulation testing is required to ensure that the repaired components meet the original standard quality as much as possible, in order to reduce the risk of accidents. Regarding the insulation series equipment, we provide a high-voltage insulation resistance tester.
3. Preventive testing of electrical equipment in operation
This preventive testing is usually conducted regularly. During the testing process, attention should be paid to the voltage withstand test of key equipment. Due to the fact that the equivalent capacitance of the tested object is often large during the operation of the equipment, and conventional high-voltage equipment cannot meet this requirement, it is best to analyze the operating characteristics of the power equipment in detail and find the best testing method based on specific line conditions.
