Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
Transformers have two coils of wire, known as the primary and secondary coils.
When an alternating current flows through the primary coil, it creates a changing magnetic field.
This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy between the two coils.

Proper maintenance and monitoring of the turbine system can help pr...
Delta T refers to the temperature difference between the generator winding and its surroundings.
Delta T is an important factor in determining the health and efficiency of a generator.
Monitoring the generator winding temperature helps prevent overheating and potential damage.
Maintaining a proper Delta T ensures optimal performance and longevity of the generator.
For example, if the generator winding temperature is 80°C a...
Vacuum drop can be caused by leaks in the system, clogged filters, or a malfunctioning vacuum pump.
Leaks in the system can cause a drop in vacuum pressure.
Clogged filters can restrict airflow and lead to a decrease in vacuum levels.
A malfunctioning vacuum pump may not be able to maintain the desired vacuum pressure.
Check for leaks by using a leak detector or soapy water.
Inspect and clean filters regularly to prevent cl...

There are two types of chillers: air-cooled and water-cooled. Common refrigerants include R-22, R-134a, and R-410A.
Air-cooled chillers use air to remove heat from the refrigerant, while water-cooled chillers use water.
R-22 is a commonly used refrigerant, but it is being phased out due to its harmful effects on the environment.
R-134a is a more environmentally friendly refrigerant, but it is less efficient than R-22.
R-41...
