Scope of application 

H series multi-function harmonic meter is a high-precision, high-reliability and cost-effective intelligent power distribution meter designed for power system, industrial and mining enterprises, public facilities, intelligent buildings and other power monitoring, intelligent control and measurement application. The series of instruments based on the function is divided into basic type E series and enhanced Z series. The E-Series can measure all power parameters in a three-phase grid. Such as three-phase voltage, three-phase current, active power, reactive power, power factor, grid frequency, with two-way power measurement function. Can measure the harmonic content in the electric wire netting, and have RS-485 digital communication, monitor switch state and electric energy pulse output function. In addition to the above E-series instruments, the Z-series enhanced functions include over-limit alarm and analog transmission output.

Products comply with GB / T22264.1-2008, G B / T13978-2008.

Instrument wiring diagram 

Wiring instructions:

The input voltage should not be higher than the rated input voltage (100V or 380V). Otherwise, the PT should be considered. For the convenience of maintenance, the use of terminal block is recommended.

Standard rated input current of 5A or 1A, greater than 5A should use an external CT. If you are using other instruments connected to the CT, the wiring should be done in series. Before disconnecting the current input wiring of the product, always disconnect the CT-secondary or shorted secondary circuits first, and use the terminal block for maintenance purposes.

To ensure that the input voltage, current phase corresponds to the same phase sequence, in the same direction, otherwise there will be power and power and other numerical and symbolic errors.

Instrument can work in three-phase four-wire or three-phase three-wire mode, the user should select the appropriate use of field wiring. Generally, there is no three-phase three-wire system without center line, and three-phase four-wire system with center line. Note that the wiring in the field must be consistent with the wiring set in the table, otherwise the instrument measurement data is not correct.
