Download Solution PDFTotal Reactive Power drawn from a three-phase balanced load where line voltage = VL, Line current = IL, Phase voltage = VP and Phase current = lP is given by:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFFormula Use:
- Active Power (P) = 3VpIp cos ϕ = √3VLIL cos ϕ
- Reactive Power (Q) = 3VpIp sin ϕ = √3VLIL sin ϕ
Where, Vp is phase voltage, Ip is phase current, VL is a line voltage, IL is line current
Solution:
We have,
- Line voltage = VP,
- Line current = VL,
- Phase voltage = VP and,
- Phase current = lP
From the above concept,
Reactive power = √3VLIL sin ϕ
