5289
100kVA, 10/12* kV Automatic Resonating Inductor for use with MIDAS System

The capacitive load range of the MIDAS system can
be increased by using this Compensating Reactor
(resonating inductor).

The 5289 provide an automatic tuneable 15kV,
100kVA inductor coil. It comes into use mainly for
power generator on-site testing. Also a separate
parallel booster supply for the standard MIDAS system
is integrated.

FUNCTION

PD Level @ Max. Output
Duty cycle at full load

The variable inductor is connected in parallel with the
capacitive test object Cx.
This configuration
constitutes a parallel resonant circuit. By adjusting the
inductor Lk the resonant point can be balanced.

In
this
resonant configuration
the
inductor
compensates the reactive power required by the
capacitor and only a smaller portion of real power
(ohmic losses) is taken from the main supply. This
arrangement enables measurement of capacitances
bigger than 1F at 15kV.
