Summarize Partial discharge level of power cable is closely related to its insulation properties and the change of partial discharge means there are defects that may endanger safe operation of the cable. So the accurate measurement of power cable partial discharge is the most effective way to check the performance of the cable insulation. As partial discharge measurement can find defects in a concentrative manner and bring very small damage to cable; experts, scholars and the international electric power authoritative organizations such as IEC, IEEE, CIGRE agree that: partial discharge test...

Insulated cylinder type reactor: switchgear cabinet, regulator and filters to be placed out of the shielded room. All other components are installed in the shielded room. Metal tank type reactor: switchgear cabinet, regulator, filter, exciter transformer and reactor to be placed out of the shielded room. Reactor tank to be connected to the shielded room wall flange directly. Bushing goes through the wall into the shielded room. All other components are installed in the shielded room. The resonance principles of the two systems are the same. Input voltage is regulated by the regulator and...

Load Diagram Shielded Room The shielded room is constructed with concrete, insulation layer, light steel structure and shielding materials. Construction of each part is to follow the requirements of the general design of test equipment plans and the prescription of GB/T12190-2006 Test Method for High Performance Electromagnetic Shielded Room. Other facts such as ventilation and sound absorption are also taken into consideration. Fully shielded partial discharge test lab Control room Insulated floor Configuration ■ Double-shielded static isolation power transformer ■ Double-shielded static...

■ Security: giving full consideration to the harm of operators and other people form high voltage test; alarm and indicator lights are used to tell the working condition of the test lab and whetherit is safe to enter. Reliability: in the design of the structure, factors such as easy to operate, process safety, rationality, economy were fully taken into account; design and material selection of critical parts are strict and reservation is made to ensure the reliability of the whole system. ■ Practicability: the whole shielded room conforms to the relative national standards, easy to...
