Voltage Drop Tester

The facility is modeled after the State Grid Corporation.Q/GDW_18172012The table source integration device designed according to the requirements of accuracy testing in the "Voltage Monitor Test Specification," featuring core technology utilizing a digital signal processor (DSP).DSPNo Chinese content provided.16High-speed Analog-to-Digital Converter Components0.05Level AC Data Collector, the source signal section is also adoptedDSPNo content provided for translation.16A sine wave or a programmable distorted wave signal source composed of digital-to-analog converters. The device also features 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, voltage exceeding upper limit time, voltage exceeding lower limit time, setpoint, power supply voltage and frequency tests (under normal operating conditions), harmonic influence tests, and more. When the power consumption of the monitor itself is ≤3VAAt the moment, each voltage output channel features simultaneous operation.10The load capacity of the voltage monitor (referring to the rated working voltage being the same, or the same rated voltage of an external power supply). During the testing of the monitor's accuracy, the process of voltage increase and decrease can be controlled by the program. Outputs can include:2～32The distorted wave of the second harmonic, its harmonic order, amplitude, and phase of harmonics relative to the fundamental wave can all be programmed.

This device also allows for online measurement of alternating voltage and harmonic content in the voltage (up to)32Next) as well as voltage distortion.

Monitor adopted8.4InchesTFTColor LCD Screen,Graph characters are displayed clearly and brightly. An industrial computer is built-in for easier operation.

Primary Features and Characteristics

1 Used for measuring the basic error, comprehensive measurement error, total voltage monitoring time, voltage above upper limit time, voltage below lower limit time, setpoint test, harmonic influence test, and more for statistical monitoring devices and recording monitoring devices.

2 The system allows for online measurement of alternating voltage, harmonic content in the voltage, and voltage distortion.

3 Chengkong Yuan can generate...2～32The distorted wave of the harmonic's sub-harmonics, the number, order, and amplitude of harmonics, as well as the phase of harmonics relative to the fundamental wave, can all be programmatically controlled.

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

5 EstablishedRS-232Interface. Through the master station software, byPCThe machine control device can perform automatic or manual inspections and handle the results accordingly.
