7RL-151

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc 7RL-151 is a current sense transformer designed for electrical measurement applications. It features a 150 A primary rating with a 150:5 secondary output ratio. The unit operates within a frequency range of 50 Hz to 400 Hz. It utilizes a free-hanging in-line mounting configuration, allowing for direct integration into busbar or cable runs without requiring a cutout panel. This component serves as a precision sensing element for converting high primary currents into standardized low-level signals suitable for downstream monitoring devices.

Current Sense Transformers Feature Summary

• Provides accurate current sensing through electromagnetic induction
• Supports wide frequency operation from 50 Hz to 400 Hz
• Enables flexible installation via free-hanging in-line design

Current Sense Transformers Applications

• Industrial power distribution monitoring systems
• Electrical panel metering and protection circuits
• Energy management and load balancing applications

Current Sense Transformers Procurement Notes

Verify the specific accuracy class and burden requirements against your downstream instrument specifications before procurement. Confirm that the physical dimensions of the window aperture match your existing busbar or cable diameter to ensure proper fitment. Check for any required accessories such as mounting brackets or protective covers that may be necessary for your specific installation environment. Ensure compliance with local electrical safety standards for the intended application region.

Current Sense Transformers Selection Notes

Select this model when a robust, non-intrusive current sensing solution is required for frequencies up to 400 Hz. The 150:5 ratio is standard for interfacing with most industrial ammeters and relays. Consider the mechanical constraints of the in-line design versus split-core alternatives if frequent disconnection is needed. Evaluate the thermal performance if the transformer will be installed in enclosed spaces with limited airflow.
