SymCom manufactures protection devices under two trade names PumpSaver and MotorSaver. PumpSavers are single phase monitors that measure power factor, voltage, and current. These measurements are collected and plugged into a microprocessor programmed with a specially calculated formula based on 20+ years of submersible pumping experience. A relay is also built into each PumpSaver monitor so that once the problem has been diagnosed, decisions can be made and the relay can trip. The trip is used to shut off power to the pump motor and prevent damage. MotorSavers are monitors that measure voltage and/or current and are used on either single phase systems or three phase systems.
