Quelle est la fonction de l'analyseur de tomodensitométrie ?

The need for power system stability and grid accuracy is expanding globally; consequently, the need for reliable instrument transformers and precision testing devices is also increasing. A necessary instrument for the testing setup is the CT Analyzer. What could be the use of this device, and who are the people that can’t dispense with it?

Core Function of a CT Analyzer

A CT Analyzer (Current Transformer Analyzer) is a specialized device used to evaluate and verify the performance of current transformers (CTs) and potential transformers (PTs) in power systems. Its primary function is to assess whether a CT meets technical and safety standards by testing parameters such as ratio accuracy, phase displacement, excitation characteristics, and burden performance.

CTs are responsible for converting high currents into manageable values for measurement and protection. If these devices are not functioning correctly, it can lead to false readings, misoperations of protective relays, and even power outages. A Analyseur de PT CT ensures that these risks are minimized by offering fast, accurate, and automated testing procedures for both CTs and PTs.

How CT PT Testing Equipment Enhances Grid Reliability

Modern Équipement d'essai CT PT offers a compact, digital solution for comprehensive field testing. Unlike traditional methods that require bulky setups and multiple instruments, a CT PT Analyzer integrates several functions into one system. It can:

• Measure CT ratio and polarity
• Analyze excitation curves and knee point voltage
• Check phase displacement and burden
• Detect winding resistance
• Generate automatic test reports

These capabilities significantly streamline the testing process, saving time while improving measurement precision. In high-voltage substations and energy metering points, using a CT Analyzer allows technicians to verify transformer behavior without disconnecting the circuit, which minimizes system downtime and enhances operational efficiency.

Why Resistance Testing Still Matters

While CT PT Analyzer systems provide a wide range of testing functions, Resistance Tester devices still play an important role, especially when assessing transformer winding integrity. Measuring the winding resistance helps identify issues like loose connections, shorted turns, or poor contacts.

By combining a Resistance Tester with CT PT testing, field engineers get a holistic view of a transformer’s performance. For example, before conducting advanced excitation and ratio testing, verifying that the winding resistance falls within acceptable limits helps avoid misleading results and ensures equipment safety.

Application Across Industries

The use of CT PT testing equipment extends beyond utility substations. Industries such as manufacturing, railways, renewable energy, and heavy engineering all rely on transformers for power distribution and metering. Accurate CT/PT performance ensures that energy is being properly measured, billed, and managed.
