Forced cooling method of transformer

  1. Apr 26, 2013 #1
    What is exactly the control system employed for forced cooling of transformer?
    'If the load on transformer increases,then temperature rises & the mass flow rate of coolant has to be increased' is it true?
    So is there any sensor/transducer for sensing (taking the feedback) of flow rate of coolant?
    If yes is it expensive?

    I guess, we can have a thermally operated flow control valves. i.e, thermostats to sense the temperature change and a transducer generating thermo-emf which could operate the flow control valve.

    My guess is the pump runs at constant speed, but the fan is controlled by a speed controller.
