Thanks to all for some good leads ....
I am going to double check generator mechanical operation, and AVR and woodward control on govenors.
The motor does start... its just that distribution system voltage drops more then desirable. The then the generator takes about 15 seconds to stabilize...
Thanks for all responses so far ....
There can be as much as 40 to 80 KW on the line when the motor is started. Yes it is the voltage dip take is the problem
I could spend some more money on the generators and upgrade the voltage regulators, add a permanent magnet field excitation and set up...
