The Types of Pad-Mounted Transformers
Pad-mounted transformers come in various types, each designed to meet specific application needs and operational requirements. The primary types of pad-mounted transformers include single-phase and three-phase transformers, but there are also several subcategories based on specific features and functionalities. Here’s an overview of the main types: 1. Single-Phase Pad-Mounted Transformers Features: Configuration: Single-phase transformers have one primary winding and one secondary winding. Applications: Commonly used in residential areas and light commercial applications where single-phase power is sufficient. Voltage: Typically used to step down distribution voltages (e.g., 7.2 kV or 14.4 kV) to lower service voltages (e.g., 120/240V). 2. Three-Phase Pad-Mounted Transformers Features: Configuration: These transformers have three primary windings and three secondary windings, arranged in either a delta or wye configuration. Applications: Used in commercial, industrial, and large residential complexes where three-phase power is needed. Voltage: Typically steps down higher distribution voltages (e.g., 13.8 kV, 34.5 kV) to standard service voltages (e.g., 208/120V, 480/277V). 3. Loop Feed vs. Radial Feed Transformers Loop Feed Transformers: Features: Have terminals on both sides of the transformer, allowing for a continuous loop in the power distribution system. Applications: Provides redundancy and flexibility in power distribution, often used in commercial and industrial settings. Radial Feed...
