Load Balancement Balance Chech = Maximum RYB −Minimum (RYB) Maximum (RYB) x 100% If the Answer is , >10 %, Then system is UNBALANCED <= 10 %, Then system is BALANCED Ex:We have three loads such as 800w connected to R-Phase, 750w connected to Y-Phase and 775w connected to B-Phase. Check the Load Balance. Balance Chech = 800−750 800 x 100% = 6.25% Therefore this system are BALANCED.
