Switchsync^TM Controller

The family of Switchsync^TM Controllers consists of

SwitchsyncTM Controller	Main Application	Controls Circuit Breaker Operation	Circuit Breaker Operation
E113	Shunt Capacitor Banks, Shunt Reactors	Open or Close	Three-pole
E213	Shunt Capacitor Banks	Open and Close	Three-pole
F236	Shunt Capacitor Banks, Shunt Reactors, Power Transformers	Open and Close	Single-pole
T183	Power Transformers	Close	Single-pole
L183	Uncompensated Transmission Lines	Close	Single-pole

All controllers have provisions for adaptive input to compensate for systematic variations in operating time of the circuit breaker. In addition, Switchsync^TM F236, T183 and L183 have provisions for two external, predictive inputs (e.g. temperature variation, control voltage). These functions make it possible to achieve added precision in the timing of the controlled circuit breaker. They also have data memory that stores information on switching times, thus permitting condition monitoring of the circuit breaker.
