To calculate the total kVA (kilovolt-ampere) requirement for powering the air conditioners, we can use the formula:
Total kVA = Number of Air Conditioners × Rating of Each Air Conditioner in kVA
First, we need to convert the HP (horsepower) rating of each air conditioner to kVA. The conversion formula is:
1 HP ≈ 0.746 kVA
Now, let's calculate the total kVA required for the 15 air conditioners:
1.5 HP × 0.746 kVA/HP ≈ 1.119 kVA per air conditioner
Total kVA = 15 air conditioners × 1.119 kVA per air conditioner ≈ 16.785 kVA
So, you would need at least a 16.785 kVA transformer (rounding up to the nearest suitable capacity) to power a company with 15 air conditioners, each rated at 1.5 HP. In practical terms, you would typically choose a standard available transformer size, such as a 20 kVA transformer, to accommodate the required load.
