The LOPS low-voltage bus overvoltage suppression device is directly connected in parallel to the bus, using technologies such as fast controllers, high-energy nonlinear resistors, overvoltage peak interceptors, and counterattack suppression. It is scientifically calculated and finely designed. LOPS fully utilizes the excellent volt ampere characteristics, huge thermal capacity, and fast response speed of overvoltage interceptors, nonlinear resistors, and counterattack suppression equipment. Generally, setting the action value of LOPS at 1.2 times the system phase voltage (customizable in special cases) can achieve good results during operation.
LOPS is directly connected in parallel to the busbar, using technologies such as fast controllers, high-energy nonlinear resistors, overvoltage peak interceptors, and counterattack suppression. It is scientifically calculated and finely designed. LOPS compensates for deficiencies such as SPD, combined overvoltage protection, and resistance capacitance absorption, completely solving the problem of overvoltage on the medium voltage main busbar.
