Answer Posted / manikiran
Frequency of a rotating machine can be found by Stroboscope..
It makes use of Stroboscopic Effect.When the frequency of
the Incident light is equal to the rotating speed (measured
as frequency of the point moving ) it appears to be
static...and the corresponding speed gives the speed of the
machine..
Or it can also be measured by a tachogenrator...

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
