j1. When designing a voltage transformer (VT) secondary circuit, fuses are always used to protect the transformer and secondary wiring from short circuit currents. A different strategy is used with current transformer (CT) secondaries. a. Explain what this different strategy is and why it is different from that of the voltage transformer. b. If a circuit breaker is supplied with three sets of current transformers on each bushing but only two are needed for metering and protection circuits, what must be done with the third (unused) CT? j1.
