Voltage Monitor Calibration Device

The facility is modeled after the State Grid Corporation.Q/GDW_18172012Integrated Device for Voltage Monitor Calibration Designed According to the Precision Test Requirements in the "Specification for Voltage Monitor Inspection" Featuring Core Technology with Digital Signal Processors.DSP) and16A high-speed analog-to-digital converter0.05Level Frequency AC Data Collector, the source signal section is also adoptedDSPNo Chinese content provided.16A sine wave or a controllable distorted wave signal source composed of digital-to-analog converters. The device is also equipped with an accuracy of1×10Our standard timer. The device is used to measure the comprehensive measurement error of statistical and recording monitors, total voltage monitoring time, over-voltage time, under-voltage time, setpoint, power voltage and frequency tests (under normal operating conditions), harmonic influence tests, etc. When the power consumption of the monitor itself is ≤3VAAt present, each voltage output path features simultaneous...10The load capacity of the voltage monitor (referring to the rated voltage of the working power supply being the same, or an external power supply with the same rated voltage for monitoring). During the testing of the monitor's accuracy, the process of voltage adjustment can be controlled by the program. Outputs can include2～32The distorted wave of the second harmonic, with its harmonic order, amplitude, and phase of harmonics relative to the fundamental wave all being programmable.

This device can also measure AC voltage and harmonic content online (up to32(etc.) as well as voltage distortion.

Display technology adopted8.4InchesTFTColor LCD Screen,Graphical characters are clear and bright. An integrated industrial computer makes operations more convenient.

Key Features and Characteristics

1 The product is capable of measuring the basic error, comprehensive measurement error, total voltage monitoring time, voltage over-limit time, voltage under-limit time, setpoint test, harmonic influence test, and more for statistical monitoring instruments and recording monitoring instruments.

2 The system can measure online the alternating voltage and harmonic content within the voltage, as well as the voltage distortion.

3 Cheng Kong Yuan can generate programmable sources that...2～32The distortion wave of the harmonic components, including the number, order, amplitude of harmonics, and the phase of harmonics relative to the fundamental wave, can all be programmable.

4 The voltage amplifier functions as a constant voltage source. Due to its lightweight design, this device is particularly suitable for on-site calibration use.

5 EstablishedRS-232Interface. Through the host software, byPCThe machine control device can perform automatic or manual inspections and process and manage the results.
