u Characteristic

(1) The 32-bit processor based on ARMTTDM-S kernel is adopted in PHILIPS, and multi-core technology is used to collect and analyze data. Each unit has a clear division of labor, which greatly improves the acquisition rate and the judgment is more accurate.

(2) when the system is single-phase arc grounding, it can be quickly transformed into metal grounding.

(3) when the system generates metal grounding or PT breaks, the device will alarm in time.

(4) The PT open triangle voltage is detected cyclically, real-time data acquisition is carried out, and the data is analyzed and calculated by digital measurement, filtering, amplification and other digital signal processing techniques. If there is a fault, the current fault type can be judged: if it is ferroresonance. The ferroresonance of 17Hz (1/3 frequency division) 25Hz (1/2 frequency division) 50Hz (power frequency) 150Hz (3 times frequency) and above can be eliminated by instantaneous starting harmonic elimination circuit.

(5) selectable automatic switching or manual switching.

(6)?the device has an accident recall function. It can record the time of 30 events and the action state of the device.
