1. Power Distribution Panels
CTs are often found in switchgear, distribution boards, and motor control centers. These are places where the electrical current needs to be monitored and controlled to protect equipment and manage power distribution.2. Substations
In electrical substations, CTs are installed on transmission and distribution lines. They help measure high-voltage currents, protect equipment, and provide data for control and relay systems.3. Transformers
Current transformers are installed in large power transformers to monitor the current passing through the transformer. This helps in ensuring safe operation and performance optimization.
4. Electricity Meters
Utility companies install CTs within commercial and industrial metering systems to measure the current consumption of larger facilities. These transformers feed information to electricity meters for accurate billing.5. Power Generation Stations
At power plants or renewable energy installations like solar farms and wind farms, CTs are used to measure and monitor the output current for control, protection, and efficiency assessment.6. Transmission Lines
CTs are installed along high-voltage transmission lines to monitor the flow of current and help regulate the transmission grid. This is important for load balancing and protection.7. Large Industrial Equipment
In industrial environments, CTs are installed on large motors, generators, and other heavy-duty equipment to measure current usage, help in load balancing, and ensure equipment safety.Current transformers play a crucial role in monitoring electrical systems, providing vital data for protection and control in a variety of locations across the power grid and industrial systems.
