A sinusoidal voltage can be described by the equation: v(t) = VM sin (ωt + Φ) or v(t) = VM cos (ωt + Φ) where v(t) Instantaneous value of the voltage, in volts (V). VM Maximum or peak value of the voltage,
It is well known that Circuit Breakers are devices which are used to break a circuit continuity and restore it again when required. Normally these are known as switching devices that can be activated manually or automatically to control the electrical power
Transformer is very simple and basic part of electrical system and considered most efficient of electrical components of machines. If we consider experimental models which are using superconducting windings then we may talk about achieving the the performance of 99.75 percent as
Transformers Fittings In order to install a medium voltage transformer below is the list of necessary fittings: Plain bi-directional rollers with blocking facilities. Skid base, lifting and jacking lugs Neutral and earthing terminals Rating and terminal marking plates Transformer Thermal Protection Temperature
First of all we should understand the concept of electric DC motors, an electric motor is a machine that converts electrical energy into mechanical energy. Most of the electric motors operate through the interaction between electric motor’s magnetic field and winding currents
Before start of the installation works exact locations of luminaries will be checked and it should be as per approved RCP (reflected ceiling plan) drawing. Installation shall be carried out by skilled and suitably experienced electricians under supervision of highly competent site
