PKTPBR series mobile package transformer substations for drilling rigs
PKTPBR series mobile package transformer substations are designed to receive, transform, and distribute three-phase AC electric power of 50 Hz frequency in electrical networks with solidly earthed or insulated neutral on the low-voltage side of the transformer.
The substation design enables relocating it together with the power transformer which allows saving time for installing the substation on a new place.
A reactive power compensation unit is embedded into the transformer substation’s low-voltage switchgear.
