Construction
The core is constructed from wound layers of high accuracy, low loss electrical grade steel. The core is evenly wound with enamel coated copper wire to ensure against potential short circuits. The core and coil assembly is encapsulated in polyurethane specifically engineered for premium dielectric, mechanical and thermal properties for use in both indoor and outdoor applications.
High Accuracy, Extended Range
The Alta Series high accuracy, extended range current transformers exceed the IEEE 0.15S accuracy standard. These CTs meet or exceed every 600V metering class CT in the industry with metering class 0.15 from 1% of nominal current through rating factor. The COS is also available in standard accuracy with or without a primary bar.
Test Reports
Each COS has a unique serial number which allows the customer to track each test record. Certified test reports are stored electronically and provided with every shipment.
