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.
A damper is a device that deadens, restrains, or depresses. Damper may refer to: 1  Dashpot, a type of hydraulic or mechanical damper, 2  Shock absorber (British or technical use: damper), a mechanical device designed to dissipate kinetic energy. 3  In electronics, a kind of diode, intended to absorb energy peaks, normally generated by inductive circuitry.
