Description

The high impedance differential protection principle has been used for many years and iswell documented in literature publicly available. Its operating principle provides verygood sensitivity and high speed operation. One main benefit offered by the principle is anabsolute stability (that is, no operation) for external faults even in the presence of heavyCT saturation. The principle is based on the CT secondary current circulating betweeninvolved current transformers and not through the IED due to high impedance in themeasuring branch. This stabilizing resistance is in the range of hundreds of ohms andsometimes above one kilo Ohm. When an internal fault occurs the current cannot circulateand is forced through the measuring branch causing relay operation.It should be remembered that the whole scheme, its built-in components and wiring mustbe adequately maintained throughout the lifetime of the equipment in order to be able towithstand the high voltage peaks (that is, pulses) which may appear during an internalfault. Otherwise any flash-over in CT secondary circuits or any other part of the schememay prevent correct operation of the high impedance differential relay for an actualinternal fault.
