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 voltage levels in electrical circuits.
They consist of two coils of wire, known as the primary and secondary coils.
The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.
Transformers...
UPS stands for Uninterruptible Power Supply, a device that provides emergency power to a load when the input power source fails.
UPS ensures continuous power supply during power outages or fluctuations
It typically consists of a battery, inverter, and charger
Commonly used in data centers, hospitals, and critical infrastructure
Examples include APC, CyberPower, and Eaton UPS systems
MCB stands for Miniature Circuit Breaker, a device designed to protect electrical circuits from overloads and short circuits.
MCB is a type of circuit breaker that automatically switches off electrical circuits during abnormal conditions like overload or short circuit.
It is commonly used in residential and commercial electrical installations to protect electrical equipment and prevent electrical fires.
MCBs are available...
Current is the flow of electric charge, measured in Amperes, while voltage is the force that drives the current, measured in Volts.
Current is the rate of flow of electric charge in a circuit.
Voltage is the electrical potential difference that drives the current.
Current is measured in Amperes (A) while Voltage is measured in Volts (V).
Ohm's Law relates current, voltage, and resistance: V = I * R.
CT and PT are electrical devices used in power systems to measure current and voltage respectively.
CT stands for Current Transformer and is used to measure high currents by stepping down the current to a lower value.
PT stands for Potential Transformer and is used to measure high voltages by stepping down the voltage to a lower value.
CTs and PTs are commonly used in power distribution systems to provide accurate measure
The last rating MCB can go up to 125 amps.
The last rating MCB can typically go up to 125 amps.
MCBs are available in various ratings such as 6A, 10A, 16A, 32A, 63A, and 125A.
The rating of an MCB determines the maximum current it can safely handle before tripping.
For higher current requirements, larger MCBs or other protective devices like MCCBs may be used.
I applied via Campus Placement and was interviewed in Apr 2024. There was 1 interview round.
Induction motor is started by providing a rotating magnetic field in the stator winding.
Start by connecting the stator winding to a three-phase AC power supply.
The rotating magnetic field is produced in the stator winding, which induces current in the rotor bars.
The induced current in the rotor bars creates a magnetic field, causing the rotor to start rotating.
Common methods of starting induction motors include direct-...
