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.
Power Transformer Sealing Systems, Part 2 – 9 minutes
Identifies a conservator-type sealed power transformer that has an air bag in the conservator and describes how the sealing system works. Identifies a gas/oil-sealed power transformer and describes how the sealing system works.
