Distribution transformers analysis and maintenance practices

 Distribution transformers Distribution transformers are normally considered to be those transformers which provide the transformation from 11 kV and lower voltages down to the level of the final distribution network. In the UK this was, until January 1995, 415 V three-phase and 240 V phase to neutral. Prior to January 1995, most distribution transformers were designed…

Direct On Line (DOL) Motor Starter

Direct On Line (DOL) Motor Starter Different starting methods are employed for starting induction motors because Induction Motor draws more starting current during starting. To prevent damage to the windings due to the high starting current flow, we employ different types of starters. The simplest form of motor starter for the induction motor is the Direct On Line…

what is Induction Motor and Types of Induction Motor

What is Induction motor One of the most common electrical motor used in most applications which is known as induction motor. This motor is also called as asynchronous motorbecause it runs at a speed less than its synchronous speed. Here we need to define what is synchronous speed. Synchronous speed is the speed of rotation of the magnetic field in a…

Solar Electricity

Solar Electricity  When sunlight strikes on photo-voltaic solar cells, solar electricity is produced. That is why this is also referred to as Photo Voltaic Solar, or PV Solar. Principles of Solar Electricity Generation of electricity by using solar energy depends on the photo voltaic effect. In photo voltaic effect, semiconductor p n junction produces electric potentia when it is exposed to sunlight. For that…
