The YPHP package is designed to feed 480 volt, three phase power from a line side facility to the train through the HEP system.
The NWYPHP provides simplified operation:
- Plug the HEP Control Loop Jumper hanging from the YPHP unit into the receptacle side of the HEP trainline on the end of the passenger car.
- Plug the 480 volt, three phase HEP system trainline into the YPHP using the HEP system plugs.
- If the top (yellow) button's lamp turns on, then the trainline control loop is complete, and it is safe to start feeding power to the train.
- Press the top (yellow) button to start feeding power.
- The bottom (red) light turns on when power is being fed to the train.
- To stop feeding power to the train, press the bottom (red) button.
The YPHP is equipped with a three phase power monitor that will shut off the power feed in the event of phase imbalance, or improper phase rotation.
