gaz sf6 insulated Voltage Transformers – Trench Group

SF 6 insulated voltage transformers are used to convert high transmission line voltages (up to 800kV) 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 transformation is essential. The reliability and security of Trench gas-insulated instrument transformers is based on over 50 years of innovation with gas-insulated units operating under a wide range of
