Four. Function description

 

1. three-phase power measurement

 

The power of the YD923F series load divider is the active power part of the generator. The measurement is based on the phase comparison between the output current of the current transformer and the output voltage of the generator, so as to measure the active power of the output current of the current transformer. This measurement method has high accuracy and reliability.

 

 

 

2. three-phase AC voltage input

 

 

 

The three-phase voltage of the generator is measured at L1, L2 and L3 (terminals 1 to 3), and the terminal N must be connected to the zero line of the generator. The AC voltage input circuit is isolated from the 24V battery circuit, and the voltage is more than 5000 volts.
