Functional Description
It is a high-performance current-generating device designed by Guodian Xigao based on years of practical experience and the latest national power industry standards, building upon the GDSL-A model. It incorporates the advantages of similar products both domestically and internationally, adopts numerical control technology, and has strong anti-interference capability. Compared with the previous generation of current generators, it uses a low-power consumption, large-capacity auto-transformer and a current transformer made of high-permeability iron core, featuring high output power, small size, and light weight. It is mainly used for primary busbar protection and complete set transmission tests of various current transformers, as well as calibration of motor protectors, air switches, switchgear, circuit breakers, protection panels, etc.
Instrument Features
- 320×240 LCD display, high-speed thermal printer.
- High-precision sensor and high-performance 14-bit AD acquisition chip.
- Human-machine dialogue full keyboard operation mode, intelligent working process throughout.
- Optional conventional current rise test, impulse instantaneous trip test, and transformer ratio polarity test, flexible and simple operation.
- Real-time display of output current and time results, intuitive and clear display.
- Perfect overcurrent protection, arbitrary setting of target output current value, current upper limit, and current withstand time.
- With return-to-zero detection function, test can only be carried out after confirming return to zero, safe and reliable.
- Approaching current rise algorithm, after reaching the set target output current, automatic current withstand timing starts, and the motor automatically returns to zero after timing ends.
- If the set output current upper limit is exceeded, the motor automatically returns to zero and an audible and visual alarm is triggered.
- Excellent software and hardware anti-interference design, multiple anti-interference methods, adapts to harsh electromagnetic environments.
- Automatic error diagnosis, easy to find and solve problems.
- Optional remote communication, door interlock alarm light and bell, open-circuit voltage calibration interface, etc.
Functional Characteristics
- Current can be smoothly and continuously adjusted, accuracy class 1.0;
- Output current is a standard sine wave, with waveform distortion rate less than 5%.
- Timing range: 0～9999ms, resolution 1ms, measurement error: 0.005% of range ±2digs.
- Can directly display the test values of primary current and secondary current, convenient for transformer ratio calibration tests.
