FIELD: electricity.
SUBSTANCE: counter comprises sensors of current for network phases "A", "B", "C", a microcontroller, an ambient temperature sensor, a square-ware generator, a register, a digital indicator, the first and second transceivers, a permanent memory, a computer.
EFFECT: increased accuracy due to taking into account dependence of active resistance of transformer windings on heating temperature and taking into account variations of ambient temperature, expanded functional capabilities of a device due to possibility of accurate determination of wear of insulation of windings at non-symmetrical load of phases.
