Description
The Single-Phase Transformers is an essential tool for experiments and demonstrations of transformer theory. It is made up of three identical transformers (except for the tertiary windings). Each transformer is inside a separate steel enclosure and all fi t onto a frame which has small wheels for ease of mobility. Each transformer has a selection of high-voltage (primary) and low-voltage (secondary) tappings to select a range of input and output voltages. They also have extra tertiary windings. The tertiary windings help compensate for any slight differences in the transformers when used in parallel. The transformers are separate units and will work as three individual single-phase transformers, or can connect to be a single three-phase transformer. All tappings are accessible, so students may link the windings to suit any of the common single and three phase connections. All tappings connect to coloured, shrouded sockets for safety. To show transformer principles clearly, the transformers operate as one volt each turn. This means that the no load output voltage is the same as the number of turns on the secondary. Thermocouples measure the temperatures of the primary windings, the secondary windings and the core of one of the transformers. The thermocouples help to measure the temperature changes in a transformers. The readings help the student to understand the temperature specification for materials used in transformers. Note: you need a suitable K-type measuring instrument (not supplied) to measure the outputs of the thermocouples. To allow a complete range of tests, We supply this product with three load banks; one resistive, one capacitive and one inductive

Single-phase double-wound transformers. Each primary has two sections with tappings at 0 V, 104 V, 120 V and 138 V. Each secondary has two sections with tappings at 0 V, 52 V, and 60 V. Each transformer has diff erent tertiary tappings:
• one transformer has 0 V, 28 V, 50 V and 52 V
• the second has 0 V, 47 V, 50 V and 52 V
• the third has 0 V, 48 V, 50 V and 52 V
Thermocouples:
Three K-type thermocouples, one fi tted to the primary, the second to the secondary and the third to the core of one transformer. Each thermocouple connects to sockets on the connection plate of the transformer.
