Product Description

 

Product Description

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.
Load Management Function - Load management terminal cooperates with AVR series intelligent compact solid insulation switch equipment. It is able to realize load management function, solve the electricity fees issue effectively for scattered residents customer, temporary customers, and the customers who fail to pay the fee frequently.
