Vidac Solutions
Partial Discharge testing is a way of detecting voids or imperfections in insulators that would lead to overheating and breakdown under normal operating conditions. Due to the nature of the signal being measured, this test is very susceptible to electronic and RF noise and a proper corona-free properly isolated test chamber is required.

CTTS Series -
Shanghai Jiuzhi Electric Co., Ltd.
CTT series cable test terminations are used to test Plastic insulated high-voltage cables. The specific advantages of this series versus conventional terminations are fast and convenient assembly. The terminations can be used for partial discharge (PD) measurements, impulse voltage testing, loss factor (tan delta) measurements and, if the cable ends are carefully prepared, for breakdown testing (step test).

YDSW Series -
Shanghai Jiuzhi Electric Co., Ltd.
SF6 insulated Test Transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and in the field, and for testing the other substation equipment. It is also the portable and easy maintenance solution. The SF6 test transformers can be flanged directly to the GIS for testing which make the partial discharge test easy and quick. These systems are particularly suited for on-site tests of GIS after installation. In the factory, they are used to test sub-assemblies and components directly in the manufacturing line.

New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.
