    UNBALANCE LOAD, REVERSE POWER IN SYNCHRONIZATION

    Hi, Sorry for the late reply, i was little bit busy these days. As Mr. Udshred advised to check fuel racks , will be the good option at this time and also the CT. I am attaching one picture of current load sharing, which is running good but if sudden load comes or the total load is very less, it...

    UNBALANCE LOAD, REVERSE POWER IN SYNCHRONIZATION

    James i have swapped the 2500 with other generator which is working fine. Gen1 Woodward working fine in Gen2 but gen2 Woodward shows same problem in Gen1. Same i did for 2301 and result was same. so above swapping confirms that both modules are ok with correct parameters. moreover i have tried...

    UNBALANCE LOAD, REVERSE POWER IN SYNCHRONIZATION

    Yes it is island mode of operation. Do not have records of frequency/Mvar but i assure you there is no change in RPM or frequency while this happens.

    UNBALANCE LOAD, REVERSE POWER IN SYNCHRONIZATION

    Hi , We have five 3512B CAT generators with Woodward 2500 synchronizing panels. Have issue with generator one only(given name 1),So when this 1 gen. is online with any other generators, will be having load sharing issue specially at the time of sudden increase of load. At this time power factor...

    Fluctuation of Generator Parameters During Low Demand Period

    Hi, I have a doubt , If generators are running in synchronization and excitation voltage have some issue with one generator so according to you it will not change the voltage of generator? we have load unbalance issue at our plant with one generator, i have checked every thing except voltage...
