Current

For the calculation the full load current of a device or circuit, you will need: The voltage of the circuit (V), The power rating of the device or circuit (W), The power factor of the device or circuit (PF), and Whether the circuit is single-phase, 3-phase or DC. Let's begin!

This AC current calculation will allow you to calculate the full load current of an AC induction motor. It will utilise supply voltage, power rating, power factor, efficiency and the type of phase to calculate a current value in amps. Let's begin!

This online tool helps you calculate the primary and secondary current of a single or three-phase transformer, as well as the turns ratio. The key parameters needed for the calculation are: phase (single or three-phase), transformer power rating (VA, kVA, MVA), primary voltage (Vp), and secondary voltage (Vs).

This tool calculates the fault current through a cable based on the following inputs: Voltage (V), Single Phase or 3-Phase current, Source fault current (kA), Cable size, Cable Length, and Cable impedance.

This arc flash calculation will allow you to obtain the arcing current value using a range of inputs, such as bolted short-circuit current, system voltage and conductor gap. Let's begin!

This tool enables you to calculate the short circuit current of a transformer using its kVA rating, secondary winding voltage rating, and the transformer's impedance in percentage.
