KEHGQ-D Type Comprehensive Transformer Characteristic Tester (Full-Function Model)
I. Design Purpose
The KEHGQ-D 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
● Supports testing of CT and PT;
● Complies with standards such as GB1207 and GB1208;
● No need for external auxiliary equipment; all tests can be completed standalone;
● Built-in miniature fast printer for on-site printing of test results;
● Easy to operate with intelligent prompts for user-friendly operation;
● Large LCD screen with graphical display interface;
● Automatically provides CT/PT (excitation) knee point values according to standards;
● Automatically generates 5% and 10% error curves;
● Can store 3000 sets of test data, which is retained after power loss;
● Supports data transfer via USB drive, readable by standard PCs, and generates WORD reports;
● Compact and lightweight ≤25Kg, highly suitable for on-site testing.

V. Operating Conditions Requirements
1. Input voltage AC220V±10%, rated frequency 50Hz;
2. The tester should be powered by a power outlet 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 parameters correspond to an ambient temperature of 23℃±5℃.
