A CT PT Comprehensive Tester can test both current transformers (CTs) and potential transformers (PTs) simultaneously using synchronized channels, precise excitation control, and intelligent measurement software. Wrindu’s advanced testing solutions integrate these functions to ensure accurate, efficient, and automated diagnostics, helping manufacturers, utilities, and service teams optimize testing performance and quality assurance.
How does a CT PT tester perform simultaneous testing?
A CT PT tester excites both CT and PT circuits and measures their responses at the same time. Using synchronized timing and multi-channel data acquisition, it compares ratio, polarity, phase, and excitation characteristics in parallel. Wrindu’s high-performance testers employ intelligent algorithms to process these signals accurately, improving productivity and reliability across manufacturing and maintenance operations.
What tests can be conducted together on CTs and PTs?
A CT PT tester supports combined ratio, polarity, excitation, burden, vector group, and winding resistance tests. Running these evaluations concurrently reduces test time while maintaining consistency. Wrindu’s equipment automates pass/fail assessments and generates unified reports, enhancing efficiency for OEMs, utilities, and laboratories focused on high-throughput quality control.
| Test Type | Function Description | Applicable Component |
|---|---|---|
| Ratio & Polarity | Verifies winding correctness | CT/PT |
| Excitation | Measures magnetic behavior | CT/PT |
| Burden & Resistance | Evaluates performance under load | CT/PT |
Which key features support accurate dual testing?
Critical features include multi-channel acquisition, synchronized signal excitation, and precision calibration. Wrindu integrates automatic compensation for environmental factors, high-resolution ADCs, and smart software to ensure repeatable results. Built-in interlocks and digital safety checks further enhance user protection and testing reliability.
Why should manufacturers adopt dual CT/PT testing systems?
Using a dual CT/PT tester reduces test bench footprint, simplifies workflows, and standardizes inspection processes. Wrindu’s instruments offer time savings of up to 40% compared to separate systems while maintaining full IEC and CE compliance. For factories and utilities, this integration ensures cost efficiency and consistent data quality across production lines.
