SERVICE DETAILS
Dial type thermometers are liquid filled in the closed system and DTT consists of Bulb assembly, capillary and Expansion bel-lows. If the temperature changes, the internal pressure of the thermometer changes as well. The pressure is transferred through capillary to a pointer shaft and thus the temperature values are indicated on scale.
OTI and BTD works without external power for its operation and indicates corre-sponding oil temperature on front panel. WTI construction is also similar to OTI, in addition to that CT are provided to meas-ure the winding temperature plus winding temperature above hot level, i.e the hot spot temperature.
WTI are provided with gradient adjust-ment through a shunt for CT secondary in-put (1A to 5A)
