Kwh Meter Standard DC Voltages / High Stability Calibration Of Electrical Instruments

1. Standard DC Voltages introduction

The XL-901 Standard DC Voltages is the latest DC energy metering standard device developed by our company. It is aimed at the needs of the current DC power meter verification on the market, follows the national verification rules of the DC energy meter, and combines the latest technology of the company, using imported industrial grade devices, can accurately measure the high-precision voltage signal of DC 0V ~ 1000V and DC 0 ~ The 600A high current signal has an accuracy rating of 0.02. The device has passed the test of Guangdong Electric Power Research Institute. Can be used for calibration of DC voltage, current or electrical energy. It can also be used for calibration of DC energy meters and provides automatic verification of power errors.

2. Display

The device adopts 800×600 liquid crystal display, which is displayed in Chinese. The interface is clear and simple, easy to operate and has good visual effect. The core module adopts 32-bit high-speed DSP, which has powerful functions, high reliability level, flexibility and adaptability.

3. Main functions

1) Establish the DC standard electric energy meter part of the 0.05-level DC electric energy meter verification device, which can realize the overall verification of the installed DC electric energy meter below 0.2.
2) It is possible to use the standard table method recommended by the JJ G842-2017 DC energy meter verification procedure to realize the error verification of the DC energy meter.
3) It can measure DC current from 0 to 500A.
4) It can measure DC voltage of 0~1000V.

4. Main technical features

1) DC standard energy meter adopts wide range range adaptive switching technology.
2) Periodic sampling of 256 points, capable of capturing rapid changes in load.
3) Use dual 24Bit AD technology to combine high sampling rate (and synchronous), high precision and low offset offset.
4) With industrial computer, 800*600 touch screen, it is more convenient to operate.
5) It is equipped with powerful and easy-to-use operating software that can run on industrial computer or PC.
