Service factor is gearbox horsepower rating over motor horsepower.
Because rating of films depends on the audience not by producers. That's why rating from producers are not mention as valid.
The KVA rating of a transformer is based on how much heat the transformer can dissipate. The BIL rating is based on how well the windings are insulated. There are other "ratings" as well. Rough calculations can be done, but tests are generally performed to prove the calculations (transformer designers will design on the conservative side to insure the transformer meets specification). These type of calculations are best done by a computer. You will struggle to determine the hot spot max temperature rise in a transformer by hand.
It's a G Rating...:D
the age rating in the UK is 15
The maximum rating or a VCB is 32 KV.The maximum curent rating is up to 3000 A.
vcb and acb
The VCB yard us basically a yard that uses the Vacuum Circuit Breaker.

High current coming now that's why use the vcb
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
.
Vcb is what is measured in a particular circuit. Vcbo is the manufacturer's maximum for base-emitter voltage.
Divide the output rating by the input rating
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.

VCB (vacuum circuit breaker) is used in HV (high voltage) applications. ACB (air circuit breaker) is used in LV (low votage) applications.
