0.05 Accuracy CT Transformer Testing Automatic Transformer Ratio Tester

Current Mutual-inductor On-site Calibration Device The product is mainly used to test one grade to 0.2S grade field current.

• Equipped with a built-in standard current transformer featuring identical ratios as the CT being tested, boasting an accuracy of 0.05.
• Features a 7-inch, 800x600 dot matrix color LCD display, capable of concurrently presenting the tested CT's ratio error, phase angle difference, and the secondary loop load on a single screen.
• Eliminates the necessity for standard CTs, current boosters, load boxes, voltage regulation boxes, and heavy current leads during on-site testing procedures.
• Automatically conducts error tests at predefined test points, streamlining the testing process.
• Includes testing capabilities for CT ratio, DC internal resistance, and voltage load box.
• Offers testing functionalities for CT ratio and internal resistance of secondary windings.
• Employs intelligent identification and alarm features to detect incorrect wiring, mismatched ratios, polarity issues, and other errors.
• Clearly indicates test results as either qualified or disqualified, ensuring ease of interpretation.
• Provides ample on-site data storage capacity, capable of storing up to 1000 groups of test data.
• Allows for the on-site printing or downloading of test data to a USB drive for convenient record-keeping and analysis.
• Comes with comprehensive test data management software for organizing and analyzing test results efficiently.
• Housed in a shock-proof, robust, and high-voltage resistant plastic packing case, guaranteeing the safety of both operators and the testing system.
