Voltage transformers VPT 100 are single-phase transformers isolated with single pole. They are designed as the sources of high voltage with the ratio 0.22/100kV or 0.38/100 kV.The power of voltage transformers VPT 100 is 3 kVA, in the short time it can be up to 7 kVA.
Magnetic circuit of voltage transformers VPT 100 is made of oriented transformer strips in the shape of “C” of core.All active parts of transformer are compound-insulated with epoxy-mixture.The transformers are supplied with the undercarriage that allows movement oftransformer.The weight of transformer including undercarriage is 125 kg.
Transformer can be supply separately or in configuration with measuring devices on side vvn.
