FIELD: power engineering.
SUBSTANCE: recorder comprises group of analogue sensors (1, 2), group of digital sensors (3, 4), analogue (5) and digital (6) commutators, the first - fourth counters (7-10), the first - fourth system memory units (11-14), permanent memory (15), microcontroller (16), timer (17), register (18), analogue-digital converter (19), clock pulse oscillator (20), D-triggers (21, 22), the first-fourth gate multivibrator (23-26).
EFFECT: expansion of functional capabilities due to provision of possibility to register parametres of transition processes of current and voltage change in electric networks in case of accidents, and at time intervals that precede emergency situation.
