eGauge Systems Rope CT Positioning
Specifications
- Product Name: Rope CT Positioning Guide
- Error Reduction: Proper installation reduces the maximum error based on positioning
- Ideal Placement: The conductor should be perpendicular to the rope CT loop and pass through the centre of the rope CT
- Tie-Wraps: Non-conductive fasteners can be used to centre the rope CT around the conductor
Positioning Guide
Rope CTs should be installed properly to minimize measurement errors. Follow the steps below for correct positioning:
- Position Number 1: Centered – The conductor should be positioned near the outer edge of the rope CT loop.
- Positions 2, 3, 4: Near outer edge – The conductor should be placed closer to the connector side of the rope CT loop.
- Position 5: Near connector – The conductor should be positioned close to the connector end of the rope CT loop.
Error Tolerance
The following table shows the maximum acceptable error based on positioning:
| Position Description | Error |
|---|---|
| Centered | < 0.4% |
| Near outer edge | < 2.0% |
| Near connector | < 4.0% |
Ideal Placement vs. Less Than Ideal Placement
For optimal results, the conductor should pass through the centre of the rope CT. However, if this is not possible, the conductor can touch points 4 and 2 of the rope CT loop, although this is considered less than ideal placement.
FAQs
Q: How should I secure the rope CT around the conductor?
A: You can use tie-wraps or other non-conductive fasteners to centre the
rope CT around the conductor.
Q: What is the maximum acceptable error for each positioning?
A: The maximum acceptable error for each positioning is as follows:
- Centered: < 0.4%
- Near outer edge: < 2.0%
- Near connector: < 4.0%
Q: Can I place the conductor anywhere within the rope CT loop?
A: No, it is recommended to position the conductor as close to the ideal
placement as possible for accurate measurements. However, if ideal placement
is not feasible, the conductor can touch points 4 and 2 of the rope CT loop.
Q: What is the purpose of the Rope CT Positioning Guide?
A: The Rope CT Positioning Guide provides instructions and recommendations
for properly installing rope CTs to reduce measurement errors based on
positioning. It ensures accurate monitoring of the conductor being measured.
Introduction
Rope CTs should be installed properly to reduce the maximum error based on positioning. Ideally, the conductor being monitored will be perpendicular to the rope CT loop, and pass through the centre of the rope CT as shown below. Tie wraps or other non-conductive fasteners can be used to centre the rope CT around the conductor.
