POWER VOLTAGE

Trench is a recognized world leader in the design and manufacture of high voltage equipment for application on electric utility and high energy industrial systems. Instrument Transformers are used to convert high transmission line voltages to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system. As such, the need for accurate and reliable voltage and current transformation is essential. The reliability and security of Trench instrument transformers is based on over 50 years of innovation with units operating under a wide range of environmental conditions.Instrument transformers also ensure suitable electrical insulation between high voltage and low voltage measuring equipment.

MAINFEATURES

General Product Design Product processSingle phase design with the possibility to couple three single devices in case of three-phase systems.

Clean Air, Oil or SF6 internal insulation

External insulation with porcelain or composite insulator Equipped with two identical secondary winding groups switchable in parallel and series connection. Thus, the output power can be evenly split to each group, avoiding compensation currents.

Temperature range from -50°C up to 40°C; dedicated features for larger ranges can be designed

Special features:

- Available to withstand moderate seismicrequirements according to IEEE 693 and specific customers’ requests (i.e. Chile ETG A.0.20).High seismic and other specific requirements on request

- Overload capability – cycle operation

- Cable discharge capability

Optimized design to manufacturing

Lean manufacturing concept applied to the whole supply chain

Optimized design allows the use of reduced numbers of components and quick customization to all customer specific requirements

Maintenance free during a long lifetime of more than 30 years

Trench Management System has been certified according to ISO 9001, ISO 14001 and OHSAS 18001 standards

Thousands of transformers are installed and in service for more than 50 years all over the world in every environmental condition – the best guarantee for the quality and reliability of our products.

Trench Power Voltage Transformers combine the attributes of an inductive voltage transformer with the application of a power transformer.

Typical applications:

- Auxiliary power supply for substations- Electrification of remote areas- Power supply during substation construction works

Trench PVT portfolio includes both SF6 and oil insulated power voltage transformers up to 550 kV.Additionally, clean air insulation is also under development up to 550 kV.

Maximum continuous output power in single phase operation 167 kVA, therefore the maximum power performance in three phase operation is up to 500 kVA

Standard output voltages on secondary side120V or 240V. Different voltages available on request.

Available according relevant IEC and IEEE Standards and specific customer requirements.
