A 20 kva 800/480 v distribution taransformer has the following resista...
Transformer Parameters:
- Transformer Rating: 20 kVA
- Primary Voltage: 800 V
- Secondary Voltage: 480 V
Resistance and Reactance Values:
- Primary Winding Resistance (Rr): 32 ohms
- Primary Winding Reactance (xr): 45 ohms
- Secondary Winding Resistance (RI): 0.05 ohms
- Secondary Winding Reactance (xs): 0.06 ohms
- Core Loss Resistance (Rc): 250 kohms
- Magnetizing Reactance (xu): 30 kohms
Explanation:
- The resistance and reactance values provided are essential parameters that affect the performance of the distribution transformer.
- The primary winding resistance (Rr) and reactance (xr) determine the losses in the primary winding when current flows through it.
- The secondary winding resistance (RI) and reactance (xs) similarly affect the losses in the secondary winding.
- The core loss resistance (Rc) is related to the losses in the transformer core, while the magnetizing reactance (xu) is associated with the magnetizing current required for the transformer to operate.
- Understanding these parameters helps in analyzing the efficiency and voltage regulation of the transformer, as well as in designing appropriate protection and control systems for the distribution network.
