In secondary hypogonadism, testosterone levels are low and levels of FSH and LH are low or inappropriately normal. Any acute systemic illness can cause temporary secondary hypogonadism. Some syndromes of hypogonadism have both primary and secondary causes (mixed hypogonadism).
Function of damper winding in synchronous machine: 1.Self starting of synchronous machine: The core concept is that damper winding being short circuited carry high current, creates magnetic flux like as induction machine.Thus there is pulling in or better torque in starting.he rotor of induction machine is mostly of squirrel cage type which is short circuited thus provides high current in start up. Damper winding in synchronous machine is placed in the coil slots and short circuited.
Accumulators And Flow Controls Accumulators Hydraulic accumulators are used to storepressurized hydraulic fluid. The accumulatorperforms the same function in a hydrauliccircuit that a capacitor does in an electricalcircuit. Dry nitrogen is used to âpre-chargeâone side of the accumulator.A piston or sometype of rubber element (bladder or diaphragm)is used to separate the hydraulic fluid and thenitrogen.Accumulators primarily will perform two functions in the hydraulic circuit:1) Supplyadditionaloilflowtothesystemataveryfastrate.ccumulators And Flow Controls Accumulators Hydraulic accumulators are used to storepressurized hydraulic fluid.
