Product Description

Power voltage transformers (Power VTs) combine the attributes of an inductive voltage transformer with the application of a small power transformer. Therefore, they are the perfect solution wherever low oltage is needed and high voltage is available.

Power VTs only have to be connected to the high voltage overhead line to provide power at low voltage. Due to this direct connection to the transmission line, the reliability of Power VTs is very high, as they arenot dependent on distribution lines that are more susceptible to outages.Trench Power VTs are designed as single-phase line to ground transformers. Byusing three devices a three-phase power supply with accumulated output power is also possible.

The Trench Power VT portfolio covers the high voltage rangeup to 550 kV. The maximum continuous output power in single phase operation is167kVA. Therefore, the maximum power performance in three phase operation is upto 500kVA.

Trench Power VTs are providing a reliable source of powerand high insulation performances for many application such as:

  • control power supply for an utility substation, switching station, power generating station, hibernating power stations
  • construction power near a high voltage transmission line
  • reliable standby power for critical loads
  • remote oil / gas pumping stations
  • flood control pumping stations
  • desalinization stations
  • hard to access locations with an overhead / underground high voltage transmission line
  • micro substations for sites with limited floor space
  • portable / easily relocatable low power substation for short -term or long-term power supply
  • powering high voltage tower mounted line switches
  • mobile phone / relay stations
  • refurbishing old substations, adding redundancy to control power supply
  • transmission line hazard lighting
  • powering refrigeration and air-conditioning plants in remote food processing/ storage facilities
  • remote railroad signaling
  • a portable testing station
