Bwr-04 Transformer Winding Temperature Thermometer Temperature Meter Gauge

General:

Model VBWR-04 series transformer winding temperature indicator is special designed for oil transformer. It is a

special-purpose indicator using the simulated temperature measurement technique to measure the temperature

of the winding of transformer.

T1 is the temperature of transformer winding which is T1=T2+T, where, T2 is the oil temperature in upper part

of the transformer, T is the raise of oil temperature. The T decided by the electricity of the transformer winding.

After the transformer is loaded, the current which is taken form the current transformer (CT) is first adjusted by

the converter, and then flows through the heating element embedded in the elastic unit, where, the current is

proportional to the load. The energy produced by the heating element increases the displacement of he elastic

unit; Therefore, the displacement of the elastic unit depends not only on the oil temperature of the transformer

upper part but also the loading current. The temperature indicated by the VBWR-04 is the summation of the oil

temperature of transformer upper part and the winding temperature rise over oil, reflection the average value of

the hottest portion temperature of the measured transformer winding.
