Application

JKW reactive power auto compensating controller issuitable for self-adjusting capacitor compensatinedevices in low voltage distribution increase theefficiency of the power transformer, reduce line loss.and improve voltage quality. On final aim it willincrease the economic and social benefits

Code and implication

unction characteristic

Adopt AC sampling technology

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

Regard the reactive power as controling physical quantity; it has high control precision.The operation of the full digital of control parameter, easy to use, put in rightplace in one step, and the data are not lost to have a power failure.Adopt and optimize the excellent control scheme automatically, reduce the times of input and cutof,improve the service life of system.Strong anti-interference abiity can resist 2000v interference pulse from power direct, and not crashing, does not lose the data, it is reliable to run steady.Digital display electric network power factors, reactive power, voltage, current (primary side) and control parameter.With two working modes of manual and automatic is convenient for user to install and debug.

With the function of over-voltage.ime iudament and disnlav and fast cutof canacitor arouo, orevent capactor arouo from running under the over-voltage condiionWith the function of available input and cutoff shocking and locking.

With the funcion for he delay time of the selectable sinle group capacitor for 200 seconds from cutoffto input, makes capactor have abundant discharcing imeaiter cutoff and reduce capacitor the impact in electric net when puttina into aaain.The input resistance of current sampling signal is smaller than 0.05; it can be taken out from measuring loops directly.Output Loops 1-16 steps
