maddatta asked Would a loss of excitation at 60% load to an AC Generator cause main and HV breakers to trip?

Obviously, if there is no excitation then there will be no voltage but and thus no power but could this loss of excitation be causing the main breaker to trip out on phase / current imbalance? The engine syncs and runs to approximately 60% load (900kW) before the main breaker trips, taking the HV breaker with it.

And got the following answer:

Yes, loss of excitation would normally cause the generator main breaker to trip, and your system may be configured to also trip the HV breakers. Loss of excitation may also trip the engine, but this is less common. However, loss of excitation should not cause a phase unbalance relay to operate. It is possible that you are seeing a negative sequence overcurrent trip due to either misconnected CTs or a severely unbalanced load. To resolve the problem, divide and conquer. You have mentioned 2 unique problems. 1. Loss of excitation. Is the field breaker or AVR tripping first? Is this followed by the unit trip, or is the loss of excitation a result of some other tripping logic operating first. 2. Phase current unbalance trip. Are the output voltages proper in magnitude and phase? Are the CTs and VTs (PTs) correctly wired? Is the unit protection configured to trip on (severely) unbalanced loads? Presumably the VTs are correctly wired, since the unit can be synchronized, but the CTs are independent of the VTs. Have the relays been tested and commissioned properly? Can you contact the engineer responsible for selecting the generator protection & relay settings? If so, make him earn his pay... Among some of the more challenging generator problems I've faced, one particular unit (about 2 MW) had internal connection problems between the stator windings and the terminal box. Luckily we found it during differential relay testing, but it could have led to loss of the unit if the commissioning tests had not been so thorough.

The relay differential perform really properly with diverse applications that are particular to power distribution and protection. The relays come with wide adjustment ranges using a scale that is definitely simple to study either in three or 4 digits as outlined by the model. These relay differential assistance in growing the flexibility of the applications, lessen the general power and upkeep charges. You will find relays that are used for common purposes which are available in trustworthy designs with fast replacement possibilities. And you will find models which can be utilized for industrial applications and heavier duty applications that operate on huge loads. These items are created to meet the lifetime industrial handle needs in the applications.
Their most recent items are the Time counter, Timer Delay, relay differential, Quick Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and several other people. The internet site delivers a detailed description of every model in several categories of relay differential couplings and sensors. These goods are exceptionally beneficial for high-risk applications. The relay differential are also accessible with options like a number of timing ranges and functions. The business is at the moment trying to find agents and dealers who can market and sell their factory created items. They’re constantly on a lookout for building new and much more reputable goods according to the needs and requirements with the business.
