The electrical equipment insulation resistance tester is designed to provide insulation resistance measurement for a wide range of electrical equipment used in power generation, transmission, distribution, and industrial applications. Insulation resistance testing is an important part of electrical equipment inspection, commissioning, preventive maintenance, and quality control.
The instrument applies a selected DC test voltage to the test object and measures its insulation resistance, helping electrical engineers assess insulation condition and identify potential deterioration. With selectable test voltages and a digital measurement interface, suitable models can be used for transformers, cables, motors, generators, switchgear, and other electrical equipment. Depending on the configuration, additional functions such as PI, DAR, timed measurement, data storage, and automatic voltage monitoring may be available.
Depending on the model specifications, common test objects include transformers, motors, generators, cables, and switchgear.
Yes. Suitable insulation resistance testers are commonly used for electrical equipment inspection and maintenance in substations.
Some models provide automatic measurement and additional diagnostic functions. Available features depend on the selected configuration.
Yes. The appropriate instrument can be selected for factory quality inspection or field maintenance according to its technical specifications.
