XL-807 Electronic Transformer Calibrator
The series of electronic transformer calibrators are designed according to the "QGDW 690-2011 Electronic Transformer On-site Calibration Specification" and other standards. They are mainly used to calibrate electronic transformers that comply with IEC61850 (-9-1, -9-2, -9-2LE) standard outputs. Calibration items include ratio error, phase error, delay, polarity, etc. They are also equipped with small signal input terminals, which can be used to calibrate electronic transformers with small signal outputs and to calibrate merging units with small signal inputs.
Product Description
Product Introduction
XL-807 Electronic Transformer Tester Mainly used for testing electronic transformers outputting according to IEC61850 (-9-1, -9-2, -9-2LE) standards. Test items include ratio error, phase error, delay, polarity, etc. Equipped with small signal input terminals for testing electronic transformers with small signal output and for testing merging units with small signal input. 。
Features
- Comprehensive test items: Supports basic error, frame transmission delay, frame publication discrete value, time synchronization and holdover, resynchronization after slip, frame integrity, harmonic verification, and other test items.
- Complete synchronization methods: Supports IRIG-B code, 1PPS synchronization signal output/input, and asynchronous delay methods for testing electronic transformer accuracy; synchronization signals support optical and electrical signals.
- Wide applicability: Built-in precision small signal source allows independent testing of merging units with small signal input; built-in FT3 digital signal source allows independent testing of merging units with FT3 input.
- Multiple extended functions: Supports protocol testing, full frame analysis, multi-channel testing, harmonic analysis, harmonic verification, transient recording, FT3 anomaly testing, composite error testing, SCD file analysis, and troubleshooting methods.
- Integrated design: Integrates high-precision AD sampling, synchronization module, digital message parsing module, precision small signal source, and precision FT3 digital source in one unit, eliminating the need for various external modules. The integrated design ensures comprehensive and reliable performance.
- High sampling accuracy: Uses 24-bit AD chip and 512 times oversampling technology to greatly expand bandwidth and improve accuracy.
- Excellent algorithm performance: Uses a 6th-order quasi-synchronous algorithm to make algorithm errors of asynchronous sampling approach zero.
- Comprehensive software functions: Can display actual waveform, verification points, standard and tested effective values, signal frequency, harmonic bar chart, and distortion rate; can statistically analyze ratio difference, angle difference mean, variance, and extreme values.
- Good human-machine interaction: Equipped with a large touchscreen display, clear and intuitive value display, and multiple interfaces including RJ45, RS232, USB, facilitating the construction of automated test systems.
