Note:the instrument must be installed on site with the supporting open and closed transformer
or roche coil.
1. General
The guide-rail harmonic meter with external roche coil and open type mutual inductor is suitable
for energy saving renovation projects in high energy consumption industries such as
smelting,steel,electric welding,semiconductor,etc.And also for power monitoring of distributed
photovoltaic grid-connected cabinet,power demand side management and other applications.The
utility model has the advantages of no need to remove primary bus,simple and convenient wiring,safe
construction,saving transformation cost and improving efficiency for users.It integrates the
measurement of all power parameters(such as current,voltage,active power,reactive power,apparent
power,frequency,power factor,etc.),multi-rate electric energy measurement,four-quadrant
electric energy measurement,harmonic analysis and electric energy monitoring and assessment
management.At the same time, it has a variety of peripheral interface for user to choose:with
RS485 communication interface,modbus-rtu protocol can meet the needs of communication network
management;The function of “remote signal” and “remote control” of circuit breaker switch
can be realized with switch quantity input and relay output.LCD display interface is adoped to
realize parameter setting and control through panel keys,which is very suitable for real-time
power monitoring system.
