Assembly Connections
1. Once the tubing is installed and the cable is terminated at the junction box,
check the sensor with the SCOUT at the junction box. This will ensure that
everything is good downhole and the rig crew can proceed with their rig down.
2. Record the parameter readings on the ESP Sensor Checklist.
3. Mount the Surface Choke and Surge Protector (Suppressor) inside the
transformer cabinet.
4. Reference FIGURE 19 & FIGURE 20 to see the electrical connections.
Surface Choke Tips
1. Make sure that the Surface Choke wires that are connected to the
transformer are braided.
2. If longer cable is needed from the Transformer to the Surface Choke, make
sure that it is rated for the Transformer voltage.
3. Each wire from the surface choke connects to one phase of the transformer.
