What is the load capacity of a 100 kVA transformer?

The load capacity of a 100 kVA transformer refers to the maximum amount of power the transformer can deliver to the load under specified operating conditions. Generally, a transformer’s load capacity is determined by its KVA rating, which indicates the maximum power the transformer can handle safely and efficiently. For a 100 kVA transformer, the load capacity would typically be 100 kVa, meaning it can provide up to 100 kilovolt-amps of power to the load without exceeding its rated capacity. Transformer load capacity depends on factors such as load characteristics, voltage levels and system configuration.

What is the full load current of 100 kVA transformer?

The full load current of a 100 kVA transformer depends on the voltage rating of the system it serves and the power factor of the load. Full load current is the maximum current that the transformer can supply to the load under full load conditions. It is calculated using the formula: Full load current (a) = power (KVA) / (square root of 3 * voltage (v) * Power factor). For example, if the 100 kVA transformer operates at a voltage of 480 volts and the power factor of the load is 0.8, the full load current would be calculated as: Full load current (a) = 100 kva / (1.732 * 480 V * 0.8) ≈ 120.9 A. Therefore, the full load current of the 100 kVA transformer would be approximately 120.9 amps.

What is the no load loss of 100 kVA transformer?

The sheltered loss of a 100 kVA transformer refers to the power loss that occurs when the transformer is energized but not supplying any load. It includes losses such as base losses (eddy current and hysteresis losses) and copper losses (due to winding resistance). The load-shielded loss represents the energy consumed by the transformer to maintain magnetic flux in the core and overcome internal losses. The magnitude of the no-load loss depends on factors such as transformer design, materials of construction, and operating conditions. For a 100 KVA transformer, the loading loss would generally be specified by the manufacturer and is expressed in watts or kilowatts.

The full capacity of a transformer refers to its ability to deliver its rated power to the load under full load conditions without exceeding its rated capacity. It is usually expressed in terms of the transformer’s KVA rating, which indicates the maximum power the transformer can handle safely and efficiently. For example, a 100 kVA transformer has a full load capacity of 100 kilovolt-amps, which means it can deliver up to 100 kVa of power to the load under full load conditions. The full capacity of the transformer depends on factors such as load characteristics, voltage levels and system configuration.
