Overview Of High Voltage Test - Insulation Test

Time:2020-06-22 Number:12

       High voltage test is a common and effective means to check whether the power equipment can operate normally. As a manufacturer of high voltage test equipment, GDZX is committed to insulation test, which is an important part of high voltage test.

       The object of high-voltage test is very wide, including generator, GIS, power transformer, high-voltage cross-linked power cable, voltage and current transformer, etc. at present, many power equipment accidents are caused by insulation fault, so insulation fault detection is undoubtedly the focus of high-voltage test of current power equipment. In other words, as long as the detection of power equipment is involved, the insulation test must be carried out, especially in the following three cases, the insulation test is regarded as the legal detection link.

1. Factory inspection of high voltage electrical equipment

       The manufacturer of high-voltage electrical equipment must conduct insulation test on all products, raw materials, etc. produced by it. Only qualified raw materials can be put on the production line, and only qualified products can be delivered from the factory. The product qualification standard shall not be lower than the relevant national standards or industry standards.

2. Insulation test after equipment maintenance

       The electric equipment will also age after long use, so it needs regular maintenance. In order to ensure the normal use of the equipment after maintenance, it is necessary to conduct insulation test to make the repair parts reach the original standard quality as far as possible, so as to reduce the risk of accidents. About the insulation series equipment, the high voltage insulation resistance tester provided by GDZX.

3. Preventive test on electrical equipment in operation

       This kind of preventive test is often carried out on a regular basis. In the process of testing, pay attention to the withstand voltage test of key equipment. Because in the process of equipment operation, the equivalent capacitance of the tested object is often large, and the conventional withstand voltage equipment can not meet this demand, so it is better to analyze the operation characteristics of the power equipment specifically, and find out the best test method according to the specific line conditions. The high-voltage test equipment provided by GDZX is series resonance device, DC high-voltage generator, ultra-low frequency high-voltage generator, power frequency voltage withstand test device, etc. welcome to purchase.

       GDZX focuses on the R & D and production of high-voltage test equipment, which is favored in the market. Welcome to inquire and purchase.
