General Information:
EPCP-IV is portable analyzer designed for analyzing current transformers and voltage transformers of protection or measurement use, which is suitable for laboratory and on-site test.

Feature:
-Comprehensive functions to meet the excitation characteristics (ie, volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference of various CTs (such as protection, measurement, and TP) It can also be used for testing the excitation characteristics, ratio, polarity, secondary winding resistance and ratio difference of various PT electromagnetic units.
-Portable and easy to operate.
-It can accurately measure the ratio difference and the angle difference, the maximum allowable error of the ratio difference is ±0.1%, and the maximum allowable error of the angle difference is ±5min. It can carry out the field test of 0.2S current transformers, and the measurement range of the ratio is 1~40,000.
-Based on the advanced frequency conversion method to test the CT/PT volt-ampere characteristic curve and the 10% error curve, the output is only a maximum of 180V AC voltage and 12Arms (36A peak) AC current, but it can handle CT tests with knee points up to 60kV.
-Automatically give knee point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), residual magnetic coefficient (Kr), saturation And unsaturated CT and PT parameters.
-The test meets various types of transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), and GB1207, and automatically selects which standard to test according to the type and level of the transformer.
-The test is simple and convenient. CT direct resistance, excitation, ratio and polarity tests can be completed with one click. Besides the load test, all other CT tests use the same wiring method.
-Full English interface, you can complete wiring and set parameters without referring to the manual: dynamically display parameter settings, automatically display related parameters according to the currently selected test item, dynamically display help wiring diagram, display corresponding to the currently selected test item wiring diagram.
-5.7-inch graphic transflective LCD, clearly visible in sunlight.
-The use of rotating optical mouse operation, simple operation, fast and convenient.
-The panel comes with a printer, which can automatically print the generated test report.
-The device can store 1000 sets of test data, and it will not be lost when power off.
