Product Description

Oil-insulated voltage transformers are used to convert hightransmission line voltages (up to 550kV) to standardized low and easilymeasurable values, which will be used for metering, protection and control ofthe high voltage system. As such, the need for accurate and reliable voltagetransformation is essential.

The reliability and security of Trench oil-insulatedinstrument transformers is based on over 100 years of innovation with oil-insulatedunits operating under a wide range of environmental conditions. Oil-insulatedvoltage transformers also ensure suitable electrical insulation between highvoltage and low voltage measuring equipment.

The oil-immersed inductive voltage transformers arecompliant to the latest international safety standard requirements in terms ofexplosion-proof, insulating material multiple chopped ageing, seismicqualification and extreme temperature conditions.

Modern production and testing facilities ensure reliabledeli very and operation over the complete life time.
