Summary

This 60-minute DVD explains basic principles of operation of transformers found in substations and switchyards. It describes power transformers and instrument transformers (CTs and PTs), and explains how these transformers are identified. Cooling systems and sealing systems for power transformers are also identified and explained.

Training Sessions

Transformer Principles – 8 minutes
Lists the main parts of a transformer. Explains how a transformer fulfills the three requirements for electromagnetic induction. Describes the relationships between primary and secondary voltages and transformer turns ratio.

Power Transformers, Current Transformers, and Potential Transformers – 13 minutes
Covers how to recognize and identify: power transformers, current transformers, and potential transformers.

Power Transformer Cooling Systems, Part 1 – 10 minutes
Describes the purpose of power transformer cooling systems. Identifies a self-cooled power transformer and describes how the cooling system works. Identifies a self-cooled/forced-air-cooled power transformer and describes how the cooling system works.

Power Transformer Cooling Systems, Part 2 – 10 minutes
Identifies a forced-oil/forced-air-cooled power transformer and describes how the cooling system works. Describes the functions of temperature gauges and level gauges on a power transformer.

Power Transformer Sealing Systems, Part 1 – 10 minutes
States the purpose of a power transformer sealing system. Identifies a gas-sealed power transformer and describes how the sealing system works. Identifies a conservator-type sealed power transformer and describes how the sealing system works.
