The high-voltage insulation resistance tester is designed for insulation performance evaluation of electrical equipment operating in medium- and high-voltage power systems.
Available in different voltage configurations, including 5kV, 10kV, and 15kV models, these instruments provide high-voltage DC insulation resistance measurement for transformers, power cables, motors, generators, and switchgear.
The instrument applies a selected DC test voltage to the test object and measures its insulation resistance over a specified period.
For electrical maintenance departments, power utilities, and industrial testing laboratories, high-voltage insulation resistance testing provides useful information for preventive maintenance and insulation condition assessment.
Different models can offer different resistance measurement ranges, output currents, voltage regulation performance, and data management functions.
The main difference is the maximum available DC test voltage. The selection should be based on the equipment's rated voltage, insulation design, and applicable testing standards.
Yes, provided its test voltage, measurement range, and output characteristics meet the transformer testing requirements.
It provides a higher available DC test voltage for applications that require such a voltage level. It is not automatically the best choice for every application.
Depending on the manufacturer and product series, different output voltage configurations and measurement ranges may be available.
