Dear all what direct consequences can be from Current transformer on generator with respect to differential protection relay?

CT's are used as inputs to the differential. If the CT is bad, or it is not wired to the differential correctly, it will cause differential current to be seen by the relay, resulting in a trip.

What is the type of generator protection to protect against unequal phase current?
differential protection
What is generator bus?
A generator bus is the bus that connects the generator to it's generating transformer.
What is a generator bus?
A generator bus is the bus that connects the generator to it's generating transformer.
What is the effect of back charging of 250MVA 15.75KV 240KV generator transformer and how many times one can back charge the generator transformer?
Generator Transformer back-charging is done because of the following reasons:- 1. To ensure the healthiness of Generator transformer after performing all the transformer related tests before synchronising with the grid. 2. To ensure all the protections of transformer before putting it into actual operation. 3. To check the polarity, ratio & connections of transformer. 4. To check all the PTs & CTs in circuit & their availability to the relays for protection & metering. 5. To check Voltage level & polarity at LAPT. 6. To perform change-over operation checks of UATs & the tie breakers with main breakers. Since all the protection system related to relays acts in the same way for forward & reverse power, we check the availabilty of each equipment before final synchronisation with the grid.
What would be minimum capacity of transformer betweed generator and 220 kV transmission line system?
At a minimum, the main step up transformer for a generator should carry 105% of the full MW output of the generator.
What is unit protection?
Unit protection is one whereby the power network system is divided into discrete zones of protection. Each zone is provided with relays and circuit breakers to allow for the detection and isolation of its own internal faults. Example of zones of protection by Unit protection schemes are Generator protection, Busbar protection, Feeder protection, Transformer protection and Motor protection.By Makenote Tshuma
Can we use transformer as a generator?
No. Transformer essentially can step up or step down voltage or provide same voltage across the secondary side. It can not generate voltage on its own. Generator is essentially a rotating device. Transformer is a static device.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is generator BCT?
BCT usually stands for bushing current transformer.
What is a static transformer?
It's a transformer that operates with AC current in and out. It's an ordinary transformer, with the term "static" used to differentiate it from rotating transformers, such as motor-generator sets.
What is 52G protection?
Generator Breaker Status
Can a transformer be used to power a deep fridge from a generator?
You power "type" must match. Most likely your generator should be able to have the fridge plug directly in, but you may indeed need a transformer to step the voltage up or down.
