RITZ DIN-Design Voltage Transformers
RITZ indoor medium-voltage voltage transformers to DIN 42600: insulation levels 3.6 to 36 kV, accuracy classes 0.2 to 6P, cast epoxy resin, made in Germany.
Product Overview
Voltage transformers step medium-voltage system voltages down to 100–400 V for meters, energy meters and relays. The representative VZN is a double-pole, large-design unit to DIN 42600 part 3, with the primary winding and the core with secondary windings cast together in epoxy resin in one step.
The secondary terminal box can be sealed for revenue metering, and the unit can be mounted in any position. The data below are for the VZN.
