Main Functions:Protective Function - It will indentify fault current automatically; realize instantaneous current cutoff, time limited current break, regular flow, directional flow, overvoltage, under-voltage, single phase ground protection of small current ground system, and cooling load start and inhibition of open circuit, and other functions.
Measurement Function - Measure three-phase current, three-phase voltage, active power, reactive power, active energy, reactive energy, peak/valley electricity, power factor and frequency, ect.
Controlling Function - It can realize on-site operation and remote control. Meanwhile, achive fault location of circuit, fault isolation automatically, resume power supply for the circuit without fault rapidly by requirement; realize automatic load shedding under low frequency, capacitor automatic cutting, automatic cutting of backup power, and other controlling functions.
Communication Function - It can report fault, operation and controlling information to appointed personnel through wireless public network or special communication network; support various kinds of communication ways and agreement; realize setting parameters modification by handhold PDA. The controller releases the instruction of self-inspection from PDA and feedback the self-inspection information to PDA terminal.
Data Record Function - Record, save and run operation and fault information automatically.
Synchronous Switching On/Off Function - According to the features of load, it searches zero crossing point automatically; adapt itself to the discreteness of switch parameter and impact of environment factors; realize synchronous switching on/off; restrain over voltage of operation and inrush phenomenon effectively, especially suitable for switching capacitor and transformer.
Intelligence Function - It can carry out on-line conprehensive analysis of power network parameters, on-line performance parameter measurement of circuit breaker, and on-line programming; cooperate with the main station pf power distribution automatic system; realize the function of remote control management of switch device, and on-site, remote or hierarchical control type power distribution automation system.Invention patents
