CT / PT Analyser for Accurate CT and PT Testing in Power Systems - Price: Rs. 0

A CT / PT Analyser is an essential testing instrument used in electrical power systems to evaluate the performance, accuracy, and safety of Current Transformers (CTs) and Potential/Voltage Transformers (PTs). These transformers play a critical role in measurement, metering, and protection schemes across substations, power plants, and industrial electrical networks. Accurate testing of CTs and PTs is vital to ensure reliable power system operation, prevent protection malfunctions, and comply with international testing standards.
This blog provides a detailed overview of CT / PT Analyser technology, explaining its working principle, key features, and practical applications. It covers important tests such as ratio testing, polarity verification, excitation curve analysis, burden measurement, phase angle error, and saturation characteristics. Modern CT / PT Analysers offer advanced capabilities including automatic testing, digital data storage, graphical display of excitation curves, and on-site testing without the need for an external power source.
CT / PT Analysers are widely used by utility companies, commissioning engineers, maintenance teams, and testing laboratories to ensure transformer accuracy during installation, routine maintenance, and fault investigation. By detecting issues such as insulation degradation, core saturation, incorrect wiring, or ratio mismatches, these analysers help reduce downtime, improve system protection, and enhance overall grid reliability.
In addition, this article highlights the advantages of using a CT / PT Analyser, such as improved testing efficiency, reduced human error, enhanced safety, and compliance with IEC and IEEE standards. It also discusses how to select the right CT / PT Analyser based on voltage class, testing requirements, portability, and reporting features.
Whether you are an electrical engineer, utility professional, or technician, understanding the role and benefits of a CT / PT Analyser is crucial for maintaining accurate measurements and dependable power system protection.
