Star delta connection is a method of connecting three-phase electrical motors.
It is used to reduce the starting current of the motor.
In star connection, the motor windings are connected in a triangle and in delta connection, they are connected in a star.
The switch from star to delta is done using a contactor.
The motor runs at a lower voltage in star connection and at full voltage in delta connection.
DG stands for Diesel Generator. It is a backup power source that works by converting diesel fuel into electricity.
DG is commonly used in areas with frequent power outages or in remote locations where there is no access to the power grid.
It consists of a diesel engine and an alternator that work together to generate electricity.
Maintenance of DG includes regular oil and filter changes, checking the battery and coolant l...
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They work on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a coil of wire.
The ratings of a transformer include its voltage rating, curr...
The voltage between neutral to ground or earth is ideally zero, but can vary depending on the electrical system and grounding practices.
In a properly grounded electrical system, the voltage between neutral and ground should be zero.
However, in some cases, such as when there is a fault in the system or improper grounding practices, the voltage can be higher.
The voltage between neutral and ground can also vary depending ...
Efficiency of a boiler can be increased by improving insulation, optimizing combustion, and regular maintenance.
Improve insulation to reduce heat loss
Optimize combustion by adjusting air-to-fuel ratio and using efficient burners
Regular maintenance to clean and repair components
Use economizers to recover waste heat
