WebJul 30, 2004 · kVA = Vline * Iline * sqrt (3) / 1000 To use the kWh, first, you must find the kW of the load, not the kWh. To do this you need to know over what time period it took to accumulate those 4,760 kWh. And you need to know if that was running continuously at a fixed loading, or if it varied. If fixed, just divide kWh by the number of hours WebJan 6, 2024 · You can calculate the line current of a transformer by using the appropriate formula for single-phase or 3-phase systems: Single-phase: I = VA ÷ E. 3-phase: I = VA ÷ (E × 1.732) Overcurrent protection. To protect the windings of a transformer against overcurrent, use the percentages listed in Table 450.3(B) and its applicable notes.
