Customer’s demand

For our high voltage test field we are looking for a choke with very high inductance. At a voltage of 6600 V, the choke should have an inductance of 6366 H (6.366.000 mH). The max. current should be at 2,3 mA, which results in an impedance of 2MW at 50 Hz

Solution

The high inductance can be achieved by using high permeable transformer metal sheets and a high number of windings. To get the dielectric strength, the winding is potted under vacuum.
