The HM6060B is a fully automatic, all-in-one testing instrument developed by Goldhome, specifically designed for protective and metering CTs/PTs. It can perform a full range of tests, including voltage-current characteristics, turns ratio, polarity, error curves, primary current injection, and AC withstand voltage, meeting the needs of both laboratory calibration and portable on-site testing.
- Complies with the requirements of GB1207, GB1208, and other standards.
- No external auxiliary equipment required; all test items can be completed with a single unit.
- Equipped with a built-in mini-printer for on-site printing of test results.
- Features an intelligent controller for simple operation.
- Large LCD screen with a graphical user interface.
- Automatically provides CT/PT (excitation) inflection point values according to standards.
- Automatically generates 5% and 10% error curves.
- Can store 3,000 sets of test data, which is retained even after a power failure.
- Supports data transfer via USB flash drive; data can be read on a standard PC and used to generate Word reports.
- Compact and lightweight (<=22 kg), making it ideal for on-site testing.
