7SHT-501

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. 7SHT-501 is an Omega 30D ANSI current transformer designed for precise electrical measurement applications. It features a 500:5 turns ratio, supporting a primary current of 500 A and a secondary current of 5 A. The unit operates within a frequency range of 50 Hz to 400 Hz and utilizes a chassis mounting configuration with a 2.5-inch inner diameter. Certified to IEC 61869 standards, it provides reliable performance in industrial environments requiring accurate current sensing.

Current Sense Transformers Feature Summary

• ANSI standard compliance for North American industrial applications
• Wide frequency operation from 50 Hz to 400 Hz
• Robust insulation level rated at 600V with 10kV BIL full wave capability

Current Sense Transformers Applications

• Integration with ammeters for direct current reading
• Connection to watt meters for power measurement
• Cross current compensation systems

Current Sense Transformers Procurement Notes

Verify the specific mounting style and terminal configuration against the application requirements before ordering. Confirm that the operating frequency range of 50-400 Hz aligns with the system's electrical parameters. Ensure the 2.5-inch inner diameter accommodates the conductor size. Check for RoHS compliance status if environmental regulations apply to the project scope.

Current Sense Transformers Selection Notes

Select this model when ANSI certification is required for current transformation. The 500:5 ratio suits high-current monitoring tasks. Consider the chassis mount design for fixed installations. Evaluate the 600V insulation rating against system voltage levels. Compare the 2.5-inch aperture with available busbar or cable dimensions to ensure physical compatibility during installation.

Current Sense Transformers Part Context

This component belongs to the Omega 30 series, specifically the 7SHT variant, which focuses on ANSI-compliant current sensing. It serves as a critical interface between high-current circuits and low-current measuring instruments. The design emphasizes durability and accuracy for continuous industrial use, distinguishing it from general-purpose transformers through its specialized frequency and insulation ratings.

Current Sense Transformers Replacement Considerations

Direct substitutes include other models within the Omega 30 series, such as the 6SHT-501 or 19SHT-501, which share similar electrical characteristics but differ in physical dimensions and mounting styles. Verify that any replacement maintains the 500:5 ratio and 50-400 Hz frequency range to ensure functional equivalence.
