5RL-801

Overview

The Sifam Tinsley Instrumentation Inc. 5RL-801 is an ANSI Metering Class current transformer designed for power monitoring applications requiring high accuracy and minimal phase angle error. It features a window diameter of 1.56 inches (40 mm) and supports a primary ampere rating of 800 A with a secondary output ratio of 800:5, resulting in a 160:1 assessment. The unit operates within a frequency spectrum of 50 Hz to 400 Hz and provides a burden capacity of 25 VA. It includes 10 kV BIL insulation and is rated for 600 V.

Feature Summary

• ANSI Metering Class construction ensures high accuracy and minimum phase angle error for reliable power monitoring.
• Window type design accommodates conductors up to 1.56 inches in diameter for flexible installation.
• Broad-spectrum frequency support ranging from 50 Hz to 400 Hz enables compatibility with diverse electrical systems.

Applications

• Integration with ammeters for precise current measurement
• Connection to wattmeters for accurate power analysis
• Cross current compensation circuits

Procurement Notes

Verify the specific application requirements against the 800:5 ratio and 25 VA burden capacity before procurement. Confirm that the operating frequency falls within the 50 Hz to 400 Hz range. Ensure the conductor size fits the 1.56-inch window diameter. Check insulation class ratings for system safety compliance. Consult official documentation for detailed mounting specifications.

Selection Notes

Select this model when high accuracy and low phase angle error are critical for metering tasks. Consider the 800 A primary rating and 800:5 secondary output for matching downstream instrumentation. Evaluate the 25 VA burden limit to ensure connected loads do not exceed capacity. Verify the 50 Hz to 400 Hz frequency range suits the source signal. Assess the 1.56-inch window size against available busbar or cable dimensions.
