TGM-220 UHL1 Current Transformer for Measurement and Protection Applications

Germetic oil current transformers TGM-220 UHL1 are large-scale current converters and are designed to generate signals to measuring instruments and protective electrical devices in electrical networks of alternating current of frequency 50 Hz with a solidly earthed or effectively earthed neutral. Transformers are manufactured with different number (up to seven) and purpose (metering, measurement and protection) of secondary windings. They require minimal maintenance costs. The presence of a chief engineer is not required during commissioning. It is sufficient to check the oil level during operation. Oil sampling is not compulsory and is at the discretion of the operating personnel.
