Product details
◆
This device is a three-phase meter source integrated device designed in accordance with the requirements of JJG124-2005 "Verification Regulations for Ammeters, Voltmeters, Power Meters, and Resistance Meters", JJG 596-1999, and JJG 307-2006. The core technology of the meter in the device is a high-precision AC collector composed of a digital signal processor (DSP) and a 16 bit high-speed analog-to-digital converter; The signal part of the source is composed of DSP and 16 bit high-speed analog-to-digital converter to form a controllable sine wave and distorted wave signal source.
The device has the characteristics of high precision, stable and reliable operation, and convenient and flexible operation.
Main functions and characteristics of three-phase AC/DC indicator calibration instrument
2.1 It can semi automatically or manually inspect the basic errors of various power frequency meters (voltmeter, ammeter, power meter, frequency meter, power factor meter, phase meter) in the power system, as well as the changes caused by factors such as voltage, current, waveform, and power factor.
2.2 The power supply section can generate distortion waves with 2-31st harmonics, and the number, order, amplitude, and phase of harmonics on the fundamental wave can be programmed.
The working frequency band of the amplifier is 40Hz~1kHz, with good linearity. The current amplifier is a constant current source, and the voltage amplifier is a constant voltage source. Due to its lightweight, this device is more suitable for on-site verification.
2.4 Equipped with USB interface. Through the upper computer software (optional), this device can be controlled by a computer for automatic or manual inspection, and the results can be processed and managed.
2.5 is equipped with a large capacity non-volatile memory that can store 300 pieces of raw data from the tested instruments for reference and upload.
2.6 The electric energy meter can be calibrated by detecting the load point or selecting the point according to the electric energy meter.
