Let's see how to calculate transformer load capacity: Obtain the transformer kVA rating. Get your load's required voltage. Rearrange the kVA equation to leave the current on one side and our parameters on the other. Resulting in: Plug in the data and solve! Or easier: use our calculator!
To begin your calculation, collect essential details regarding your transformer, such as: – Rated power (kVA or MVA) – Rated primary voltage (V1) – Rated secondary voltage (V2) – Rated primary and secondary current (I1 and I2) These values are typically mentioned in the nameplate or given by the manufacturer. 2. Determine apparent power
To calculate a three-phase transformer's load capacity, use the straightforward formula: Say your household load voltage is 2000V, and the load current is 250A. For this load capacity, the suggested size of the transformer is 1000kVA. My load voltage is 1500V, what kVA transformer should I get?
The formula for the load current corresponding to the maximum efficiency of a transformer is: The percentage resistance, reactance, and impedance of a transformer are calculated using the rated parameters of the transformer. These values are expressed as a percentage of the rated voltage or full-load current.
These quantities are measured at full load current with the voltage drop, and expressed as the percentage of normal voltage. The efficiency of the transformer is given by the output power divide by the input power. Some of the input power is wasted in internal losses of the transformer. Total losses = Cu loss + Iron Loss
