What is the result of under frequency to the system.
Answer Posted / guest
since the system is designed with a standard frequency say
50Hz or 60 Hz, if the frequency goes low, the following
effects will happen:
1. induction motor will run with low speed and consume more
current.
2. transmission cost/losses will be more.
3. capacitive reactance will be more.
4. metering device will record more power

How can we find the breaking capacity of a Load breaker switch (LBS) fed from 11 kv supply??ex:50KA, 26kA etc???detailed step vice answer pls.
ht side line to earth voltage
a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
