7SHT-122

Current Sense Transformers Overview

The Sifam Tinsley 7SHT-122 is an ANSI metering class current transformer designed for power monitoring applications requiring high accuracy and minimal phase angle error. It features a chassis mount configuration with terminal connections and a 2.5-inch inner diameter window. The unit operates within a frequency range of 50Hz to 400Hz and provides a turns ratio of 1200:5, converting primary currents up to 1200A into a standardized 5A secondary output for instrumentation.

Current Sense Transformers Feature Summary

• ANSI metering class construction for precise power monitoring
• Chassis mounting design with integrated terminals
• Wide frequency operational capability from 50Hz to 400Hz

Current Sense Transformers Applications

• High accuracy power monitoring systems
• Industrial electrical distribution panels
• Energy management instrumentation

Current Sense Transformers Procurement Notes

Verify the specific model designation against official Sifam Tinsley documentation to confirm chassis mount configuration and terminal type. Ensure the required inner diameter matches the 2.5-inch specification for conductor compatibility. Confirm that the 1200:5 ratio aligns with the primary circuit load requirements and that the operating frequency range covers the system's fundamental frequency.

Current Sense Transformers Selection Notes

Select this component when ANSI compliance and low phase angle error are critical for metering accuracy. The chassis mount style suits panel integration where space constraints differ from window-type installations. Consider the 50-400Hz range if the application involves variable frequency drives or harmonic-rich environments common in modern industrial power systems.

Current Sense Transformers Part Context

This part belongs to the Omega 30D series of current transformers manufactured by Sifam Tinsley Instrumentation Inc. The series is engineered for robust performance in demanding electrical environments. The 7SHT variant specifically denotes the ANSI-rated chassis mount configuration, distinguishing it from non-ANSI or panel mount alternatives within the broader product line.

Current Sense Transformers Replacement Considerations

Direct substitutes include other ANSI-class current transformers with identical 1200:5 ratios and compatible mounting dimensions. Verify that replacement units maintain the same 50-400Hz frequency response and terminal configuration to ensure seamless integration without modifying existing panel wiring or cutouts.
