◆ Features

(1) Utilizing a 32-bit processor based on the ARMv7TDMI-S core from PHILIPS, the data collection and analysis are carried out using multi-core technology. With clear division of labor among units, the collection speed is significantly improved.

Judgment is more accurate;

(2) In the event of single-phase arc grounding in the system, it can be quickly converted to metallic grounding.

(3) The device promptly alarms when the system generates a metallic grounding or PT open circuit.

(4) Conduct cyclic testing on the PT opening triangle voltage, real-time data collection, and analysis and calculation of the data through digital measurement, filtering, amplification, and other digital signal processing techniques.

If a fault occurs, identify the current fault type; if it is ferromagnetic resonance, instantly activate the detuning circuit to eliminate 17Hz (1/3 octave), 25Hz (1/2 octave), 50Hz (power frequency), and 150Hz (3rd harmonic).

Ferromagnetic resonance at frequencies of 100 kHz and above

(5) Available for automatic or manual switching;

(6) This device features an accident recall function, capable of recording the time and action status of up to 30 events.
