Transformers are rated in kVA because it indicates the maximum amount of power that can be safely handled by the transformer.
kVA rating is used to determine the maximum load that a transformer can handle without overheating.
It takes into account both the voltage and current ratings of the transformer.
kVA rating helps in selecting the right size of transformer for a specific application.
For example, a 100 kVA transforme...
MCCB stands for Molded Case Circuit Breaker.
MCCB is a type of circuit breaker that is commonly used in electrical distribution systems.
It provides protection against overcurrent and short circuit faults.
MCCBs have adjustable trip settings for different levels of current protection.
Examples of MCCB manufacturers include Schneider Electric, Siemens, and ABB.

Types of transformers include power transformers, distribution transformers, autotransformers, isolation transformers, and instrument transformers.
Power transformers are used to step up or step down voltage in power transmission systems.
Distribution transformers are used to step down voltage for distribution to consumers.
Autotransformers have a single winding and are used for voltage regulation.
Isolation transformers p...
IR test stands for Insulation Resistance test which is used to measure the resistance of insulation material.
IR test is used to check the quality of insulation material used in electrical equipment.
It helps to detect any insulation failure or breakdown in the equipment.
The test involves applying a high voltage to the insulation material and measuring the current flowing through it.
The measured resistance value is compa...
CT stands for Current Transformer, a device used to measure electrical current.
CT is a type of transformer that steps down high current to a lower, measurable level.
It is commonly used in power systems to measure current flowing through a circuit.
CTs are also used for protection purposes, such as detecting overcurrent or short circuits.
CTs can be either solid-core or split-core, with the latter being easier to install.
