Power cable insulation testing VLF high voltage generator

Cantidad : 888   Precio : 8000-15000USD/set

Power cable is an important part of the power system, and its insulation performance is directly related to the safe and stable operation of the power system. However, with the increase of the cable's service life, the cable insulation material will gradually aging, insulation performance will gradually reduce, so it is particularly important to carry out regular insulation testing of power cables. This article will introduce the importance of power cable insulation testing and methods.

1. DC withstand voltage test: DC withstand voltage test is a commonly used insulation testing method for power cables, by applying a high DC voltage, the insulation resistance and leakage current of the cable is detected, so as to judge the insulation performance of the cable. 2.
2. AC Withstand Voltage Test: AC Withstand Voltage Test is an insulation testing method closer to the actual working condition, by applying a certain frequency of AC voltage to test the insulation performance of the cable. This method can better detect the defects and problems of cable insulation materials.
3. Dielectric loss measurement: dielectric loss measurement is a commonly used insulation testing method for power cables to determine the performance of cable insulation materials by measuring the tangent of the loss angle of the capacitor. This method can detect small changes in dielectric loss, which is important for detecting early cable insulation aging and other problems.
4. local discharge detection: local discharge detection is a non-destructive testing method, through the detection of power cable internal partial discharge generated by acoustic and electromagnetic waves to determine the insulation performance of the cable. This method can discover the defects and problems existing inside the cable in time, which is of great significance for guaranteeing the safe and stable operation of the power system.
