Introduction

IED is designed for the selective, reliable and fast differential protection of
busbars, T-connections and meshed corners. IED can be used for different
switchgear layouts, including single and double busbar with or without transfer
bus, double circuit breaker or one-and-half circuit breaker stations. The IED is
applicable for the protection of medium voltage (MV), high voltage (HV) and extra
high voltage (EHV) installations at a power system frequency of 50Hz or 60Hz.
