I have 12MW gas engine based power plant its running parallel with grid. my problem is When cpp run in island mode(without geb) that time geb transformer power factor is 0.2 lagging. When cpp run with parallel that time power factor is 0.94 lagging So how can i maintain power factor ofgeb transformer in island mode 0.9 lagging?
SPCL,
1 2852hi can you give any body fault level calculation, generator fault level calculation,transformer fault level calculation for system fault level with equation? i have 3.3kv generation voltage three gas gen sets, one is 1.9MW,2nd is 2.5MW,& 3rd is 3.8MW & i have 11 kv generation voltage one gas gen sets is 3.8MW, we are step up to 22kv by transformer

1910Lux 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
