Transformers 1.3 Transformer Basics 1 How to size a transformer Transformer size is determined by the KVA of the load. Load voltage, or secondary voltage, is the voltage needed to operate the load. Line voltage, or primary voltage, is the voltage from the source. Single-Phase has two lines of AC power. HID Ballast Wiring Diagrams Ballast

Wiring Diagrams for HID ballast kits including Metal Halide and High Pressure Sodium Lighting ballasts. Most magnetic HID ballasts are multi-tap, meaning they can be connected to several different voltages.

Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-wire three-phase circuit is usually more economical than an equivalent two-wire Page 1. . . back of manual of possible equipment damage.Catalog
