Ohio Semitronics, Inc. - Current Transformer Open Circuit Protection

Current Transformer secondaries are designed to operate into a very low resistance load - ideally, a "short" circuit. When a CT secondary encounters an open or high resistance circuit, it quickly becomes a step-up voltage transformer. It then presents dangerously high voltages that are at a minimum, unsafe, and frequently destructive to the device insulation and surrounding components. (read more)
