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.
Danger of Open Service Neutral. According to the NEC, metal parts of service equipment shall be grounded to the earth. The purpose of grounding the metal parts to the earth is to protect persons and property from fires by limiting voltage on the metal parts from lightning [250.4(A)(2)].f the grounded (neutral) service conductor is open, neutral current will flow onto the metal parts of the electrical system. When this occurs in a wood frame construction building, neutral current seeking a return path to the power supply will travel into the moist wood members.
