Like other types of transformers, dry-type transformers are electrical devices used to transform voltage and current. They perform the following primary functions in various applications:
1. Voltage reduction or boosting: Dry-type transformers convert high input power voltage to a low voltage suitable for load equipment, or vice versa. These transformers are widely used in power transmission and distribution systems.
2. Circuit isolation: Dry-type transformers isolate the electrical connection between the input power source and the output load, preventing cross-current interference and electrical short circuits, providing additional safety.
3. Voltage stability: Dry-type transformers regulate the input power supply, ensuring a stable voltage level within the power system to ensure proper operation and protection of equipment.
4. Current conversion: Dry-type transformers can also convert AC current from the input power source into other types of AC current, such as three-phase AC and single-phase AC.
5. Current and voltage measurement: Dry-type transformers can be used to measure and protect current and voltage within systems, including current transformers and voltage transformers.
