Device independently sets up overload alarm section, can throw and move back;
(6) zero sequence direction alarm or tripping operation, the route selection of Neutral Grounding through Resistance in Electrical system is tripped:
Centering point grounded system via resistance device only need change the zero sequence TA being different from small earthing current system, and during zero-sequence current wiring, zero sequence TA secondary Same Name of Ends is all near bus bar side, and residual voltage can calculate or external;
(7) busbar grounding alarm:
When device access TV open delta voltage, this function can judge the single-phase earthing of small earthing current system, and device provides four kinds of throwings to move back mode altogether, can move back type send different alarm signals according to throwing.
(8) TV broken string alarm and latch-up protection:
According to following two criterions, device judges that TV breaks; Criterion one: a certain line voltage be less than 70V simultaneously arbitrary phase current be greater than 0.04In; Criterion two: negative sequence voltage is greater than 8V;
(9) breaker failure alarm:
After device sends tripping operation pulse 2s, switch does not still return without conjugating and protecting, then device sends out breaker failure warning information;
(10) electric current Threshold Crossing Alert:
The throwing of electric current Threshold Crossing Alert is moved back and is automatically completed by program with definite value, automatically drops into the input of three-step charging, gets 90% of three-step charging current ration reckling, as alarm current ration simultaneously;
(11) protective current loop is abnormal:
Under normal circumstances, protection gathers biphase current or three-phase current amplitude and not to have relatively large deviation.When out of phase electric current differs by more than 20%, and during more than 10s time delay, then device sends out the abnormal self-inspection information of current circuit.
