Indicator of short circuit for overhead lines of high voltage class 110 kV, network frequency 50 Hz, with installation on the wire of the controlled line. Detection of emergency processes with short-circuit current flowing more than 25A. Model IKZ-B41 is the simplest modification with visual indication only, without means of communication, it is convenient to place in a clearly visible area, for example, at the entrance of overhead lines in substations.
Separate indication of stable and unstable line faults by means of super-bright LEDs with visibility up to 100 m (daytime) and up to 500 m (nighttime). Change of settings by means of DIP switches for 10 positions. Power supply - lithium battery (8.5 Ah), standby life 10 years.
Protection degree of the indicator is IP 68 according to GOST 14254-96. On overhead lines of high voltage class, a Faraday cage is used to protect the indicators from induced voltage.
