    What does k stand for in relay protection

    The K factor (or zero-sequence compensation factor) adjusts the measured impedance for the phase-to-ground fault loop by accounting for the contribution of zero-sequence currents. Without proper. Why are circuit breakers called 'Q'?" The prefixes 'K' and 'Q' are from standards about 'item designation'. Countries using American standards use IEEE Std 315-1975 / ANSI Y32. 2, Graphic symbols. In the design of electrical power systems, the ANSI Standard Device Numbers denote what features a protective device supports (such as a relay or circuit breaker). These types of devices protect electrical systems and components from damage when an unwanted event occurs, such as an electrical. The protection and control devices in electrical equipment can be referred to by numbers, with appropriate suffix letters when necessary, according to the functions they perform. For you and me, it's just a relay. The list of ANSI device numbers with their acronyms is as given below.
