FIELD: faults testing.
SUBSTANCE: device for non-destructive testing of faults in the electrical network contains an introductory board to which two electrical installations are connected through the electrical network, transition resistance and current sensors. A high-voltage divider, a low-pass filter, an amplifier, an analog-to-digital converter, a microcontroller, and the first and second indicators are connected in series to the electrical network. The first and second electrical installations are connected to the electrical network through current sensors, the outputs of the current sensors are connected to the microcontroller through amplifiers-limiters.
EFFECT: improvement of a device for non-destructive testing of faults in the electrical network.
