Converters for high-voltage transformer test fields

According to IEC

For mobile high-voltage transformer test facilities

PowerTech converters are used as a voltage source for isolation tests, endurance tests, etc.

Very high outputs up to 4 MVA and parallel operation are possible

High level of EMC expertise is required because test routines with partial discharge measurements are carried out during converter operation

Short-circuit proof, single-phase operation, full stabilisation of harmonics from THD and DC offset
