Other requirements

1. Current/voltage sampling

The fixed load cabinet has load current sampling, and the load voltage sampling includes load end sampling and generator end sampling conversion, so as to eliminate the influence of the line on the measurement results.

2. The intelligent console should have an external display terminal interface VGA or DVI to meet the requirements of Party A for extended display.

3. Installation requirements

1) The load cabinet is fixedly installed outside the workshop.

2) The intelligent console is installed in the ground control room and connected to the load cabinet through control cables.

4. The data and waveform on the load cabinet can be transmitted to the intelligent console and displayed.

5. When the load is expanded, it can only be controlled on the main console, and the control on the slave console fails, and the test data can only be displayed on the main console, and the total load parameters can be displayed.

6. The supplier shall provide Party A with the structure diagram of the Load bank within 10 natural days after the signing of the contract, so that Party A can prepare the installation foundation of the Load bank in advance.

7. The supplier shall provide the buyer within 10 natural days after the signing of the contract: the electrical installation and wiring diagram of the supplied equipment.
