|One of our gas turbine generator unit "1st stage rotor
ground fault" alarm was occured several times. we tried to
measure some voltage vulue ground fault protection relay
(UNS3020a made by ABB and we measured the value of:
u+: 300 – 350mVAC
The unit still running and the alarm was reset. As of 6pm
yesterday and unitl now no alarm happened again. I our
protection relay was defective?
|how can we use isolator as breaker
|what is load balancing. what maximum load diffence is
allowed between phases.
|What should be the minimum and maximum ohmic value for
|6 MVA transformer secondary is rated for 725V at no load.
The incommer ACB is rated at 690 V, 3200 Amp. Would there
be any effect on performance of ACB due to lower voltage
|Is there any thumb rule for cable selection for any current
|which pole motor is best ?4 pole motor or 6 pole motor,why?
|What is the difference between RCD & RCCB, Where it can be
|How do I know if a transformer is saturated?
I am doing the simulation of the saturation of a
transformer, but what parameter tells me when a transformer
is saturated? How do you calculate? is on the plate?, there
is a rule that can help me? How could model? I understand
the saturation occurs when the flow can no longer bind to
the other winding, this is given to certain current, this
current is the same that appears as the highest in the bale
Thank you for your help
