Liquid level indicators

Unexpected or accidental oil leakages can occur in a transformer’s lifetime. A clear indication of the oil level inside the transformer tank and in the on-load tap-changer provides important information about the health of the transformer. 

Hitachi Energy provides a wide range of liquid level indicators, conventional or with analog and digital output, which help to improve safety and reliability by monitoring the condition of the transformer.
