Cheap Price CT Analyzer Current Transformer Tester CT PT Tester
A Transformer CT PT Tester, also known as a Current Transformer Potential Transformer Tester or CT PT Analyzer, is a specialized instrument used to test and analyze the performance of current transformers (CTs) and potential transformers (PTs).
Turns Ratio Test: The tester can measure the turns ratio of CTs and PTs, which is the ratio of the primary to secondary windings' turns. This test helps verify if the transformers are correctly designed and providing accurate current or voltage transformation.
Polarity Test: The tester verifies the polarity of the transformer windings to ensure they are connected correctly. Proper polarity is essential for accurate measurement and coordination with protective relays.
Ratio Error Test: This test determines the accuracy of the transformers by comparing the measured ratio to the rated ratio. Any deviation from the expected ratio can indicate a fault or degradation in the transformers' performance.
Excitation Curve Test: The tester measures the magnetization characteristics of the CTs and PTs by applying different voltages and recording the resulting currents. This test helps evaluate the saturation behavior and linearity of the transformers.
Burden Test: The tester measures the burden impedance of the CTs and PTs to ensure they fall within the specified limits. Burden impedance affects the accuracy and performance of the transformers under different load conditions.
Winding Resistance Test: The tester measures the resistance of the transformer windings to assess their condition and detect any potential faults like loose connections or high resistance joints.
Saturation Test: The tester checks the saturation characteristics of the transformers by applying increasing voltages until saturation occurs. This test helps determine the transformers' operating limits and performance under high-magnitude current or voltage conditions.
Demagnetization: The tester can perform a demagnetization process to remove any residual magnetism in the transformers.
