The product of normal system voltage and short circuit
current at the point of fault is fault level and is equal to
3 Vph(normal) x Isc for symmetrical fault in 3 phase
system.It is expressed in KVA or MVA

Answer / amit khamesra

Short circuit levelof the system defines its mechanical
strength to bear the enormour fources and heat developed by
short circuit current. To revamp a systm from 40 KA to 50
KA capacity, more no. of insulator suppors are required
along with increase in busbar current carrying capacity.

Answer / isaac p

Fault level is a point where the normal operation level
has been exceeded and the system shuts down or other
components are called to rescue the situation.

Answer / tarak mehta

It is the value which is exceed the normal value from where

Lux meter is the measuring device to measure the lux level of lighting fixture. in industrial sector two types of lighting fixture is being used as street lighting purpose 1. HPSV (Sodium) and 2. HPMV (Mercury). HPMV having white light which is an combination of red, blue and yellow colour, while HPSV haivng Yellow lighting. in HPSV red & blue colour will be absent. during measurement of the lux level of HPSV and HPMV fixture. 1. Lux meter can measure the actual lux level of both fixture? 2. or it will show false reading for HPSV fixture light as it has only yellow light present. please give me answer
