Attachment 8 - CT Split and Split Core.pdf

This is an attachment containing technical specifications and product cut sheets for current transformers and flexible split-core CT devices used in power factor correction and power quality improvement applications.

The document includes detailed specifications for two primary product lines: Weschler Instruments' FlexCore flexible split-core current transformers and Square D's AccuSine current transformers with split-core design. The FlexCore transformers feature silicone rubber encapsulation, operate across a temperature range of -45°C to +200°C, and are available in seven opening sizes with 1 or 5 Amp secondaries and 0.333V or 1.0V secondary options. Specifications detail insulation levels of 0.72 kV and 10 kV, operating frequency of 50-400 Hz, thermal factors ranging from 1.25 at 30°C to 1.0 at 55°C, altitude ratings up to 4000 meters, and accuracy ranges from 2% to 3% depending on amperage ratings. The AccuSine transformers employ directional silicon steel cores with copper secondary windings encapsulated in silicone rubber, with similar environmental protections. Detailed reference tables provide specifications for both round and rectangular split-core design variants, including maximum load ratings (ranging from 500A to 5000A), inside diameters, burden capacity, and weight information. Secondary leads feature spade connectors with custom lead lengths available, and all units remain flexible across the specified temperature operating range.
