How to accept test capacitors

How to accept test capacitors Although the capacitor has undergone factory tests when leaving the factory, it may be damaged during transportation, loading and unloading. Users must also conduct acceptance tests according to the following contents before use: (1) Appearance inspection: Check whether the capacitor shell, porcelain sleeve, outlet guide rod, and ground bolts are […]

How to choose the zero-sequence voltage and zero-sequence current protection device for capacitor bank

How to choose the zero-sequence voltage and zero-sequence current protection device for capacitor bank The zero-sequence voltage protection device is suitable for capacitor banks with single-star wiring. Usually, the neutral point of three single-phase voltage transformers or a three-phase five-column voltage transformer is connected to the neutral point of the capacitor bank. When a capacitor […]
