Answer Posted / ahmed allam
if you mean protection of for example power plant
so the most important parameter is scan time of
the controller must be very fast so action be very fast

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
