This template simulates the energy consumption, production and cost of various setups including batteries, combined heat and power (CHP) systems, electric vehicle charging and renewable energy sources. It can be used for minimising operational costs in energy management systems. Let's begin!

This calculator computes the maximum demand of current based on the specific load group, its phase types and quantities for single unit households (a house, shed or individual living unit) based on the procedures provided in the AS/NZ 3000 Wiring Manual.

This template allows you to calculate the specific energy cost of household appliances and electrical machines based on a given cents per kilowatt hour rate! We will provide you with a cost-per-week or monthly rate. Let's begin!

This template will allow you to calculate the motor speed of an AC induction motor using the supply frequency and the number of pole pairs within the motor. Let's begin!

This template allows you to perform an electric motor torque calculation using motor speed and specified power rating. Motor torque, speed and power are directly related and are some of the most important considerations when selecting a motor. 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 template assists you in calculating power in a circuit by inputting values for voltage and current. It can either calculate the total power in a circuit or the power dissipation of particular electrical components. Let's begin!

This template uses the frequency of an AC source and the capacitance value of a capacitor to calculate its reactance. Reactance is an important property of capacitors and inductors that arises due to the changing direction of the current flow in AC circuits. Let's begin!

This template will use frequency and inductance input parameters to provide a reactance value. Reactance is a property of AC circuit components that is similar to resistance. The difference is that while resistance opposes the current flow, reactance opposes the change in the current. Let's begin!

This template will enable you to calculate a power value for real, apparent and reactive power in kW, kVA and kVAR units. You will need to know either the line voltage or phase voltage, the phase current/line current and the power factor. 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.

This calculator will allow you to determine an appropriate battery size in Amp-hours given load, supplied voltage, duration, battery type and charge. Let's begin!

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 functions as both an AC and DC voltage drop calculator, allowing you to determine the voltage drop across a length of wire based on the input voltage, rated load current, and distance.

This template will use Ohm's Law to calculate voltage in a circuit given current and resistance. 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).

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 calculation is for the generator fault current given a generator power rating, rated voltage, and impedance in base percentage. Let's begin!

Calculation of the generator load current is an important task that ensures that your generator runs at an optimal level and is not overloaded. This is important for maintaining the safety and efficiency of your generator system. Let's begin!
