KEHGQ-C Type Comprehensive Transformer Characteristic Tester
I. Design Purpose
The KEHGQ-C Type Comprehensive Transformer Characteristic Tester is designed for automatic testing of protective and metering CTs/PTs, suitable for both laboratory and on-site testing.
II. Main Features
1. Supports testing of both CTs and PTs;
2. Complies with standards such as GB1207 and GB1208;
3. No need for external auxiliary equipment; all tests can be completed standalone;
4. Built-in miniature fast printer for on-site printing of test results;
5. Easy to operate with intelligent prompts for user-friendly experience;
6. Large LCD screen with graphical display interface;
7. Automatically provides CT/PT (excitation) knee point values according to standards;
8. Automatically generates 5% and 10% error curves;
9. Can store up to 3000 sets of test data, which is retained after power loss;
10. Supports data transfer via USB drive, readable by standard PCs, and generates WORD reports;
11. Compact and lightweight (≤22 kg), ideal for on-site testing.

V. Operating Conditions
1. Input voltage AC220V±10%, rated frequency 50Hz;
2. The tester should be powered by a socket with protective grounding. If there is an issue with the protective ground connection or if the power supply lacks an isolated connection to ground, the tester can still be used, but safety is not guaranteed;
3. The corresponding ambient temperature for parameters is 23℃±5℃.
