6 SmartBypass Control
The SmartBypass has 2 distinct modes of operation, the performance and operation of the modes is described
below.
1. Monitoring Mode – The normally closed contactor S1 is closed. The SmartBypass bypasses the Smart
Wires series compensation devices across its terminals so no reactance is injected. The SmartBypass can
transmit telemetry data in this mode. When the SmartBypass senses a line current which exceeds its rated
tolerance, it automatically bypasses the Smart Wires series compensation devices with fast-acting
antiparallel SCR switches (S2), entering monitoring mode within 1 millisecond.
