Transformer ratings are specified in terms of voltage, current, and power.
Transformer ratings indicate the maximum voltage and current that can be applied to the primary and secondary windings.
Power rating specifies the maximum power that can be transferred through the transformer.
Ratings also include frequency, insulation class, and temperature rise.
Examples of transformer ratings include 10 kVA, 480V/240V, 60 Hz, Cla
Transformers are of two types - Step-up and Step-down transformers.
Step-up transformers increase voltage while decreasing current
Step-down transformers decrease voltage while increasing current
Other types include isolation transformers, autotransformers, and instrument transformers
Isolation transformers are used to isolate a circuit from the power source
Autotransformers have a single winding and are used for voltage re...

AC motor speed can be controlled using methods like voltage control, frequency control, and pole changing.
Voltage control: Adjusting the voltage supplied to the motor to change its speed.
Frequency control: Changing the frequency of the AC power supplied to the motor to control its speed.
Pole changing: Altering the number of poles in the motor to adjust its speed.
Using variable frequency drives (VFDs) for precise speed

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used in power distribution, voltage regulation, and electrical isolation
I applied via Naukri.com and was interviewed before Jun 2023. There were 3 interview rounds.
The gearbox oil grade is typically specified by the manufacturer based on the requirements of the gearbox.
Gearbox oil grade is determined by the viscosity and additives needed for proper lubrication.
Common gearbox oil grades include SAE 80, SAE 90, and SAE 140.
Consult the manufacturer's specifications or maintenance manual for the recommended gearbox oil grade.
