There are the following types of insulation tests: design test, production test, handover acceptance test, preventive maintenance test, and fault location test. Different test types depend on different test purposes and application areas, and different insulation test procedures have different characteristics. And we can also see that using the HT2500, these tests can be easily and conveniently performed with satisfactory results. This will be discussed separately for different test types.

1. Design test

Design tests are typically used to determine the performance of electrical devices in the laboratory. Design tests are typically performed by manufacturers on newly designed devices or devices purchased from other companies for product design. The design test checks if the device is faulty. Insulation resistance testing is performed prior to the manufacture of any product.

2. Production test

In order to ensure that products that are working properly in the laboratory are still functioning properly after production, each product must be tested for production. Production testing is performed by the manufacturer to meet specifications and standards and to ensure quality control. Insulation resistance tests are performed on new products and equipment before they are put into

service. In production testing, product defects are generally revealed. Production testing is usually non-destructive. It is necessary to test whether the performance of the components to be installed on the production line meets the insulation requirements. Since the purpose of this test is to verify that the component has sufficient dielectric strength, rather than the factory acceptance test of the overall equipment, no specific parameters are required, but only verification is required.
