CONVENTIONAL FLUID STATION SERVICE VOLTAGE TRANSFORMER

170 kV

Station Service Voltage Transformers utilizing Conventional Fluid insulation provide low-voltage power directly from HV potential in substations, with the proven Trench design and highest reliability.

CHARACTERISTICS

  • For voltage levels up to 170 kV
  • Single phase units with power outputs <10 kVA up to 100 kVA
  • Complies with the specific requirements of the SSVT standard (dual IEC and IEEE logos)

GENERAL

  • Designed and manufactured without partial discharge
  • Scalable design with 3 units in 3-phase systems or additional units connected in parallel
  • No maintenance for a long life of over 30 years

MAIN FEATURES

Resilience and reliability,
even in extreme operating conditions

Design

A safe and reliable design based on Trench's inductive voltage transformers with conventional liquid insulation. The original design of the VTs has proven itself in practice for over six decades.

Seismic

Exceptional seismic performance as a consequence of the optimized design of the insulator.

High Voltage Insulation

The optimum field grading is achieved by a fine condenser grading system that has been designed specifically for this particular application.

Low voltage Power supply

Optimized high-voltage coil for power output and specially designed low-voltage winding for power output. This allows a correspondingly large cross-section to be connected to the secondary outputs.

Modular design

Allows the use of a reduced number of components.
