Hi all,
i have been asked to lead a close out report on our last project on the electrical and C&I areas. i was just wondering if anyone might have done some work on these type of reports and have info which might be of help. this being a first for me i am keen to deliver a good and...
Hi all,
i have posted under standards, but just on the off chance someone might know here,
can someone confirm if the latest MV(6.6kV) ANSI code calls for the control compartment (local control, metering, protection etc) to be removed from switchgear panel and located elsewhere
mant thanks...

Hi All,
interesting one for the board.
we have 150 Mwatt, 181.2 MVA generator (onto 110kV system), when operated at unity power pactor or slightly lagging we have no problems. however when run at full load and 0.85pf lagging we get vibration levels rising rapidily after about three hours (i.e...

Hi all
An issue has arisen in relation to the Electrical Design that we use in the WIndfarms for 38kV connections. It is in relation to the connections of the Grid connected transformer and whether it should be star(38kV)-star (20kV) or star(38kV)-delta (20kV). Both configurations have been...
Hi Folks
I am reviewing a tripping Matrix for turbine/Generator set for the first time, Is it possible to cross check with a standard or any useful websites?
thanks for any help

Hi all,
I have a problem on site. Ths gas turbine must be capeable of running continously in Augmented mode, hence higher output. however the generator is rated to run at class B temperature with class F insulation. the higher throughput means the generator now operates above class B (close to...

HI all,
I wish to do some research on performance testing of solid fuel boilers. I know of one standard for power plant performance testing DIN 1942,
Im looking for other possible references/standards or websites for information purposes on power plant performance testing, boiler and turbine...
Hi folks
Besides the usual standards available, are there any sites where guidelines for earthing procedures in power plants are laid out. im espeically interested in following guidelines for construction of the earth grid during plant construction, bonding procedures and sizing of earthing...
hi all, i just have two simple questions
could someone be so kind as to explain why we use IPB's instead of high voltage cables in power plants? what are the advantages
2) with IPB's the current is carried on the inside conductor, will the same current be induced on the outer conductor...
Hi Folks,
Looking through a shop test procedure for generator, I have problems trying to setermine how they calculated the Potier Reactance. i have looked at IEC 60034-4 where it is specified, but it is still not clear to me,. any help on this would be greatly appreciated,
Kind regards

hi folks,
what are people opnions on differential protection on large motors (6.6kV motors 1MW +)? is it necessary anymore. old company policy here states it is, my opnion is its not.
as we have s/c protection.
