Transformer OTI-Oil temperature indicator internal parts and external parts explained in Tamil
Sensing bulb-it helps for sensing oil temperature to OTI and explained inside sensing bulb and working principle
Thermostatic expansion valve mechanism-it will helps to operate the OTI mechanism
Link leverage mechanism- it will helps to transfer the movement from thermostatic expansion valve to OTI indicator needle
Super heated spring –internal part of the thermostatic expansion valve
Capillary tube-pressure reduction in sensing bulb liquid pressure
Mercury switch-working principle compare with water bottle example for easy understanding
