Current Transformer Secondary Circuit Load Tester

KEHEL-B Type Current Transformer Secondary Loop Load Tester

I. Instrument Overview
       The KEHEL-B type current transformer secondary loop load tester is primarily used for on-site detection of the actual secondary load of CT/PT. It features a single-unit output voltage range of 0–50V. During testing, only the rated secondary value of the transformer needs to be set. Upon completion, the test results are directly displayed. It supports on-site printing, data storage, eliminating the need for manual recording and other cumbersome tasks. Easy to operate and convenient to use, it improves work efficiency and is a cost-effective high-tech product.
II. Precautions
      1. For personal and equipment safety, please read the manual carefully before use and strictly follow the operating specifications;
      2. Before testing, ensure the instrument is reliably grounded. Do not touch any test terminals during the experiment;
      3. The company reserves the right to modify this manual. In case of discrepancies between the product and the manual, the actual product shall prevail.
III. Features of the Secondary Load Tester
      1. Safe and reliable: Uses single-phase AC220V input power, with both working power and power supply sharing the same input port. The design is more scientific and reasonable, ensuring safer and more reliable use;
      2. Complies with national maintenance regulations: The device outputs real voltage and current values, with a standard sine wave waveform and frequency of 50–60Hz, meeting relevant national maintenance standards;
      3. Comprehensive functionality: Capable of testing CT/PT secondary load items, easily achieving multiple uses with one device;
      4. Simple wiring: Utilizes a single power input port; only two test ports are required to complete CT/PT load testing. The wiring is safe and straightforward, making it highly suitable for on-site use, effectively reducing labor intensity and improving work efficiency;
      5. Easy operation with color large-screen display: The operation is simple, intuitive, and convenient, with Chinese prompts. The color large-screen display makes operation even easier;
      6. Compact and lightweight: The product is small in size, light in weight, and portable, making it ideal for on-site use.
