Product Description
Main Features
According to the national standard G / T 20847.7 electronic voltage transformer and G / T 20847.8 electronic current transformer requirements, electronic transformer (ECT / EVT) has two kinds of analog output and digital output. The calibration system is based on the virtual instrument, which can realize the measurement of difference, difference between analog and digital output of the electronic transformer, according to GB / T20847.7 / 8 electronic transformer standard and IEC61850 communication standard. On - line Measurement Comparison of Transformer. For the majority of power testing, measurement, construction units to provide a removable electronic transformer calibration device.
The calibration system can complete the electronic current transformer calibration can also complete the electronic voltage transformer calibration. The system is divided into current standard channel, the voltage standard channel, the current measured channel, the voltage measured channel, calibrator data processing platform. The current standard channel consists of a booster, a standard current transformer, and a standard converter. Current measured by the current channel channel, the school was composed of transformers. The calibrator obtains the electric parameters of the standard current sensor and the calibrated current sensor through the collector, and uploads these electrical parameters to the computer in the standard format. The computer data processing platform compares the two signals at the same time, The school current sensor error situation, display and record the measurement results. Voltage standard channel from the booster, the standard voltage transformer, the standard converter components. Voltage measured by the booster channel, the school was composed of transformers. The operating principle is the same as the current calibration system.
System Features
● comply with G / T 20847.7 / 8, IEC61850-9-1 standard;
● powerful, suitable for G / T 20847.7 / 8-based electronic current, voltage transformer analog output interface, digital output interface verification.
● Based on virtual instrument design, simple operation, flexible configuration, system stability;
● High accuracy and reliability. Accuracy level of 0.05, can be used for 0.2 grade electronic current transformer and 0.2 electronic voltage transformer alignment and calibration.
● Using high-precision interpolation method to synchronize to ensure that the school transformer and the standard transformer data collection to strict timing synchronization, reliability, practical greatly improved.
System functions
● Flexible configuration, can be configured according to different needs / electronic current transformer calibration / electronic voltage transformer calibration;
● Calculate the difference between the transformer and the standard transformer current / voltage rms,
● Display current, voltage, frequency and other information of the current wire to facilitate the comprehensive assessment of the school parameters;
● Display the real-time waveform of the transformer output, and related settings, and automatically save the calibration data, generate reports;
● Flexible configuration of test parameters, test range, test frequency, sampling points and other relevant information.
