Transformer 400 KVA 11/433 KV IS 1180 Level 1
400 kVA (kilovolt-ampere) transformer is a specific type of power transformer with a power rating of 400,000 volt-amperes. The kVA rating represents the apparent power capacity of the transformer, which is a combination of both the real power (measured in watts) and the reactive power (measured in volt-amperes reactive or VARs). It’s important to note that the real power, also known as active power, is the portion of the apparent power that is actually used to perform useful work, while the reactive power is associated with magnetizing currents and voltage phase shifts.
- Capacity: The transformer’s capacity is 400 kVA, which indicates its ability to handle up to 400,000 VA of apparent power. This rating accounts for both the real power (in watts) and the reactive power (in volt-amperes reactive or VAR) in an AC electrical system.
- Voltage Levels: A 400 kVA transformer can step up or step down voltage depending on its configuration. The specific voltage levels depend on the primary and secondary windings. For example, it could take a higher voltage input on the primary side and provide a lower voltage output on the secondary side, or vice versa.
- Applications: A transformer of this size is commonly used in medium-sized industrial facilities, commercial buildings, and other applications where there’s a need to manage electrical distribution or to adapt voltage levels.
- Three-Phase Systems: Transformers of this capacity are often used in three-phase systems, which are common in industrial and commercial settings. Three-phase systems provide more efficient power distribution compared to single-phase systems.
- Installation: Installation of a 400 kVA transformer requires proper planning, electrical expertise, and compliance with safety regulations. Transformers of this size may require specific infrastructure to handle.
