incompatiable avr changing
incompatiable avr changing
(OP)
hi all
i am planning to change an obsolete stamford avr (series 3 part number 450-11700) with datakom product avr 8 automatic voltage regulator for old 250 kva cummin generator set. this is because we need the generator working as soon as possible and we dont have the compatiable avr at hand.(avr-8 can work with generator of this capacity)
the problem is that the stamford avr get the supply from the permenant magnet generator at the end of the alternator and sensing voltage from the main stator.but since the datakom avr dont support the permenant magnet generator i am planning to use the datakom avr without the permenant magnet generator out put connected with only the sensing from the main stator out put (which also used as supply for the avr) and by connecting the exitation terminal connected to the excitation out put of the avr.
Will it work properly?
best regards

The PMG is an option that is often added to a generator that is suitable for use with a non PMG AVR.
However I have had issues with insufficient residual voltage when changing from one AVR to another economy AVR.

I have replaced the avr and it is working well.
