Application


JKW-16 reactive power auto compensating controller is suitable for self-adjusting capacitor compensatine devices in low voltage distribution increase the efficiency of the power transformer, reduce line loss, and improve voltage quality. On final aim it will increase the economic and social benefits.



Function characteristic

1.Adopt  AC sampling technology

2.Digital integration, filtration, not sensitive to the harmony wave.

3.Regard the reactive power as controlling physical quantity;  it has high control precision.

4.The operation of the full digital of control parameter, easy to use, put in right place in one step, and the data are not lost to have a power failure.

5.Adopt and optimize the excellent control scheme automatically, reduce the times of input and cutoff, improve the service life of system.

6.Strong anti-interference ability can resist 2000V  interference pulse  from power direct, and not crashing, does not lose the data, it is reliable to run steady.

7.Digital display electric network power factors, reactive power, voltage, current (primary side) and control parameter.

8.With two working modes of manual and automatic is convenient for user to install and debug.

9.With the function of over-voltage, under-voltage judgment and display and fast cutoff capacitor group, prevent capacitor group from running under the over-voltage condition.

10.With the function of available input and cutoff shocking and locking.

11.With the function for the delay time of the selectable single group capacitor for 200 seconds from cutoff to input, makes capacitor have abundant discharging time after cutoff and reduce capacitor the impact in electric net when putting into again.

12.The input resistance of current sampling signal is smaller than 0.05Ω;it can be taken out from measuring loops directly.

13.Output Loops 1-12 Loop
