4 Power Transformer Protection Devices Explained In Details

Buchholz (Gas) Relay. The Buchholz protection is a mechanical fault detector for electrical faults in oil-immersed transformers. The Buchholz (gas) relay is placed in the piping between the transformer main tank and the oil conservator. Pressure Relay. Many power transformers with an on-tank-type tap changer have a pressure protection for the separate tap changer oil compartment. This protection detects a sudden rate-of-increase of pressure inside the tap changer oil enclosure. Oil Level Monitor Device. Transformers with oil conservator(s) (expansion tank) often have an oil level monitor. Usually, the monitor has two contacts for alarm. Winding Thermometer. The winding thermometer, shown in the figure below, responds to both the top-oil temperature and the heating effect of the load current.

Transformer Monitoring - Online Dissolved Gas Analysers

A permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. It allows for the individual measurement of Moisture in Oil (H 2 O) and the key gases Hydrogen (H 2), Carbon Monoxide (CO), Acetylene (C 2 H 2) and Ethylene (C 2 H 4) dissolved in transformer oil. This extra data from the HYDROCAL 1005 reduces the amount of maintenance time because the probable cause of any faults will have been established before action takes place.Get price
