Intronduction
1.1usage scope
HY reactive power auto-compensation controllers is suitable for automatically
adjusting of low voltage distribution sytem capacitor compensating device to make
power factor get user’s predetermined state, increase service efficiency of power
transformer reduce line loss,and inprove the voltage of power supply.
Function and Characteristics
1.Accounting switch on and switch off capacity by the fundamental wave reactive
power may avoid any form and switch on and switch off vibration,and be able to demons-
trate the eletrical network power factor correctly under the harmonic wave situation.
2.High,messuring accuracy of power factor,wide display scopt.
3.Real time display total power factor(pF)and fundanental wave power factor(DPF).
4.Real time display voltage distortion current distortion rate.
5.There are five codes output types for user’s selection.
6.16 steps output at most.
7.Friendly human-computer interface,easy to operate.
8.Various Controling pattern whole digits unable,easy to operate.
9.Two working modes of auto running and manual running.
10.Over-voltage and under-voltage protective funtion.
11.Voltage harmonic wave over norm protective function.
12.Data can not loss as it has breaking power supply protective function.
13.Current signal switch on impedance is lower than 0.01.
Service condition
1.Not over altitude 2500m.
2.Ambient temperature-25℃~50℃.
3.Air humidity is less than 50% at 40℃.And is less than 90% at 20℃.
4.working in the medium which not any corrasive gas,electric conduction dust inflammable
and explosive matters.
5.The installation site without shrewd vibration.
