The Zenith™ surface choke is a 5,000-V interface module that allows the Zenith surface interface unit (ZIU) or Zenith surface panel (ZSP) to communicate with the downhole gauge.

The choke is capable of being connected directly to the high voltage electrical submersible pump (ESP) power cable and protects the ZIU or ZSP from the high voltage using a very large inductance. Fuses, transient protection devices, and voltage clamps within the choke module protect from ESP faults propagating into the low voltage ZIU and ZSP.
Features and Benefits
- Protects the ZIU or ZSP from high voltages
- Simplifies hook up:
- Three high voltage terminals connect to the ESP cable and two low voltage spade terminals connect to the ZIU or ZSP
- Single 8-mm grounding point that must always be connected for safe operation
Applications
ESP operations with Zenith E Series downhole gauge
