Complete transformer substations of internal installation (KTP) with capacity from 25 to 3150 kVA with voltage up to 35 kV inclusive carry out reception, conversion, distribution and transit of electrical energy. KTP are designed for power supply of facilities of raw fields development, oil and gas transport, industrial production, power grid facilities and other facilities from the main and/or backup power supply source with (without) AVR, with rated current of busbars up to 4000 A and rated current of electrodynamic resistance of circuit breakers up to 150 kA.
Structure of KTPP
Single-transformer KTP consists of an input device on the high-voltage side, a power transformer, a switchgear on the low-voltage side.
A double-transformer CHPP has two input devices on the high-voltage side, two power transformers and a switchgear on the low-voltage side. In the operation of two-transformer KTP provides...
