Answer / ekanadam naik

yes we ca operate dg set with transfer but voltage and
freqency must be matched, with help of PLC,

Answer / a. venkatesh

All the power source it may be transformer or Alternator
(DG-DC power generator).
For parellel operation synchronisation is important. I.E
Voltage level, frequency, phase angle should be equal for
the both sources.

For checking the synchronisation previously DARK LAMP
METHOD was used. Now a days special relays used for this
purpose. Relays MES 120(Schneider), 7UT relays in Siemens.

Answer / sangram

yes, we can Theoretically do it. we want to use aditional
relay and some equipments like Reversepower relay, DF/DT.

Answer / meka sekhar

theoretically DG can be operated parallelly with
transformer as long as voltage, frequqncy, phase angle are
within limits. However, in industrial practice, only
momentarily paralleling will be done between DG &
transformer. Sometimes if they want to check loading of DG,
it can be paralled with transformer so that it will not
affect loads which are connected to bus.

Answer / sangram patil

Yes, called as synchronizsation of DG & EB of both. for
this parallel operation we want to concentrate on Voltage,
Frequency & Phase angle of both of equal.
and for Auto loading & Autobalancing we want to use
Woodward, C&S OR scnhider make relay.

Answer / ram

no dg set can not be connected with x-mer DG can not give
constant freq.
