Due to voltage fluctuations and power load changes in power systems, power capacitors that perform reactive power compensation may suffer from low voltage hazards. In order to protect capacitors from damage to ensure normal compensation work, generally speaking, enterprise users need to take some measures to do low voltage protection. So, how to achieve low voltage protection?

1. Introduce voltage sensor. By monitoring the change of power supply voltage, low voltage problems can be found in time and corresponding measures can be taken. Sensors can collect voltage data and send it to a control center or monitoring system for analysis and processing.

2.  Use automatic capacitor switches. The switching state of the capacitor can be automatically controlled according to the voltage change. When a low voltage event is detected, the switch automatically disconnects the capacitor to avoid the capacitor continuing to be affected by the low voltage.

3.  using capacitor protection equipment. Including over voltage protection device, short circuit protection device and over temperature protection device. Overvoltage protection prevents capacitor damage due to excessive voltage, short circuit protection prevents capacitor failure due to short circuit, and overtemperature protection prevents capacitor damage due to overheating.

4. regular maintenance and testing. The operating status and parameters of capacitors should be checked regularly to discover and eliminate potential problems in time. In addition, it is also important to clean the capacitor regularly to remove dust and dirt, as these dirt may reduce the performance of the capacitor.

The harm. It can be seen that low voltage protection is very important to ensure the normal operation of power capacitors. The capacitor can be effectively protected from low voltage by introducing related protection devices
