ACREL 100 x 80II Current Transformer for Electrical Monitoring
ACREL 100 x 80II Current Transformer for Electrical Monitoring is a solid-core AC current transformer designed to measure high currents in low-voltage electrical distribution systems. It has a 100 x 80 mm configuration with a 104 x 85 mm through opening and supports primary current ratios from 600-800 A up to 2500-4000 A, depending on the selected configuration. The transformer provides a 1 A or 5 A secondary output and is designed for connection to electrical measuring instruments and power monitoring equipment.
The ACREL 100 x 80II Current Transformer for Electrical Monitoring is designed to provide an AC current signal for electrical measuring instruments. The 100 x 80II version is intended for applications where a larger busbar opening is required while retaining a conventional solid-core current transformer arrangement.
The transformer is installed around the conductor or busbar being measured. Primary current flowing through the opening produces a proportional secondary current, allowing compatible meters and monitoring equipment to measure the circuit current without directly carrying the primary current through the measuring instrument.
For the 100 x 80II configuration, Acrel specifies primary current ratios from 600-800/5(1) through to 2500-4000/5(1). The available accuracy and rated burden vary according to the selected current ratio.
How it works
- The primary conductor or busbar passes through the transformer's central opening.
- AC current in the primary conductor creates a corresponding secondary current.
- The secondary output is rated at 5 A or 1 A, depending on the selected transformer configuration.
- A compatible measuring instrument can use this secondary signal for current measurement and power monitoring.
Why choose this product
- Large through opening: The 100 x 80II configuration has a specified through size of 104 x 85 mm, making it suitable for larger conductor and busbar arrangements within the stated dimensions.
- Multiple current ratio options: The model is available across several high-current ranges from 600-800 A through to 2500-4000 A.
- Suitable for measurement systems: The transformer is designed as an AC current sensing component for use with electrical measuring instruments.
- Defined accuracy and burden options: Acrel specifies the accuracy class and corresponding rated burden according to the selected current ratio.
Benefits
- Provides an isolated secondary current signal for compatible measuring equipment.
- Allows high AC currents to be measured using standard 1 A or 5 A CT inputs.
- The solid-core construction provides a fixed magnetic circuit around the measured conductor.
- Available in several current ratio configurations to suit different electrical measurement requirements.
