SL3000-X
Current Harmonic Sensor
Category:
The SL3000-X series current harmonic sensor primarily monitors the motor circuit current. The motor circuit input end is powered by high and low voltage switchgear. The current harmonic sensor senses the main circuit current signal and outputs it to the sensor edge terminal for digital signal processing and analysis. It extracts current harmonic characteristic values and waveforms to diagnose motor rotor faults, air gap eccentricity faults, winding faults, etc. It features simple installation, safety, and high reliability.
