kVA to Amps conversion formulas are used to calculate current from known kVA rating of AC electrical power equipment. Given below is the list of formulas: Single Phase kVA to Amps: I = (kVA * 1000) / E Two-phase Four wire AC kVA to Amps: I = (kVA * 1000) / (E*2) Three phase kVA … Read more
Electrical transmission lines are responsible for bulk transportation of electricity from one point to another. Various components of transmission lines play their role for the successful transmission of power from plants to utilities. Given below is a brief overview of 10 components used in transmission lines: Phase Conductor A conductor is the main component which … Read more
Electrical quantities such as resistance, voltage, power, inductance and capacitance can have very large values. For example a power station can generate 1,000,000,000 watts of power, similarly an inductor can have a value of 0.00001 H. To keep things straight forward, a common practice is to use prefixes. Each prefix represents a power of ten. … Read more
Induction is the most popular type of machine in the electrical industry. Given below are the 7 Basic concepts you need to know about Induction Motors. What Induction Motor is named so? The rotor current in electrical machines is often induced by physically connecting wires. However, in an induction motor, the rotor voltage is induced … Read more
HP to Amps formulas are used to calculate current provided that HP (horsepower) is known in any circuit. Given below are the formulas: HP to Amps Formula In case of DC (HP x 746)/(E x %Efficiency) Single phase AC (HP x 746)/(E x %Efficiency x PF) Two phase four wire (HP x 746)/(E x %Efficiency … Read more
Electrical and Electronics Engineering is all about electricity. Electricity has some fundamental properties associated with it. This magnitude of these properties is expressed in terms of quantities and their units. Given below is a list of these quantities, their symbols, units, and abbreviations. While majority of derived units are takes from SI system, unit for … Read more
A current transformer is an instrumentation transformer which steps down the AC current to a safe level (usually 1 Amps or 5 Amps full scale) so that relays and measurement devices can easily deal with current. Our electrical power system carries heavy currents of about hundreds of amps at very high voltages. Electrical measurement devices … Read more
