Answer / Dinkar Rai

The fault level is calculated by multiplying the short-circuit current (Isc) by the phase-to-phase voltage (Uph). It's important to note that the exact method for calculating the short-circuit current depends on the type of power system, load, and protection scheme. For example, in a three-phase system, the fault level can be calculated as follows:

Fault Level = Isc * Uph

why Line voltage =1.732XPhase voltage what mean by 1.732

Dear All, In a 400V power system, ratio of three current transformers installed incoming switchgear is 4000/1. Maximum three phases short circuit current of this system is 48kA. One CT is installed on neutral of upstream transformer (6/0.42kV, solidly earthed) for 51G protection. Would you please inform me about the correct CT ratio of this current transformer (on neutral)?? Thanks a million
