Electrical Engineering – KVA Calculator


KVA Calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection. To calculate KVA, you need to enter the known values of voltage and the current into the respective fields. These two values are applied to the below formulas used in this KVA Calculator to calculate the unknown quantity KVA. For single phase connection, KVA can be mathematically derived from this below formula Single Phase KVA Calculation Formula; KVA = volts x amps / (1000)

For three phase connection, KVA can be mathematically derived from this below formula
Three Phase KVA Calculation Formula; KVA = volts x amps x √3 / (1000)

Voltage Calculator is also used in electrical engineering to measure the unknown voltage by two known quantities KVA and current applied to the below formulas. For single phase connection, voltage can be mathematically derived from this below formula
Single Phase Voltage Calculation Formula; volts = KVA x 1000 / (amps)

For three phase connection, voltage can be mathematically derived from this below formula
Three Phase Voltage Calculation Formula; volts = KVA x 1000 / (√3 x amps)

Current Calculator is also used in electrical engineering to measure the unknown current by two known quantities KVA and voltage applied to the below formulas. For single phase connection, current can be mathematically derived from this below formula
Single Phase Current Calculation Formula; Amps = KVA x 1000 / (volts)

For three phase connection, current can be mathematically derived from this below formula
Three Phase Current Calculation Formula; Amps = KVA x 1000 / (√3 x volts)
