Electrical Submersible Pump (ESP) panels provide the surface‑mounted controls required to operate submersible pumps used in oil production. These panels supply stepped‑up voltage to the downhole pump and manage all operational, protection, and monitoring functions. Control Innovations supplies ESP panels in both full‑voltage and VFD‑driven configurations, giving producers flexibility in how they operate and protect their pumping systems.
An ESP panel provides the surface controls needed to power and operate an electrical submersible pump. The panel works with a step‑up transformer and terminal box to deliver high‑voltage power to the pump motor while managing start/stop control, protection functions, and optional variable‑speed operation.
Key Features
Control Innovations ESP panels typically include:
- Full‑voltage or VFD‑driven pump control
- Step‑up transformer and terminal box integration
- Backspin timer to prevent premature restarts
- Inputs for Presco switches, over‑pressure shutdown, and E‑stop circuits
- HAND / AUTO selector for Pump‑Off Controller (POC) operation
- Remote speed reference for VFD units (4–20 mA or 0–10 V)
- Optional analog output for current feedback to POC systems
- Built‑in line filtering, with enhanced filtering available
This provides a complete, field‑ready control solution for ESP installations.
VFD‑Driven ESP Panels
Variable‑speed ESP panels offer:
- Reduced inrush current during starting
- Lower mechanical stress on pump motors
- Ability to slow the pump to reduce start frequency
- Remote speed control from a POC
- Current feedback output for monitoring
These features help extend pump life and improve operational flexibility.
Full‑Voltage ESP Panels
Full‑voltage ESP panels provide:
- Simple, direct‑online pump operation
- Standardized wiring and terminal numbering
- Compatibility with POC systems
- Optional current feedback device for monitoring
These panels offer a straightforward, cost‑effective control method.
Protection & Operational Logic
ESP panels include features that support safe and reliable operation:
- Backspin protection to ensure the fluid column has settled
- Shutdown circuits for pressure switches and E‑stops
- Standardized field wiring terminals
- Line filtering to reduce electrical noise
This helps prevent damage to the pump motor and surface equipment.
Available Options
Control Innovations offers a range of options for ESP panels, including:
- Accessory power for chemical injection pumps
- GFI‑protected outputs for heat trace
- Site run and fault indication lamps
- Live Presco test logic
- Site stands or pedestal legs
- Dead‑front doors
- Harmonic filters to meet IEEE‑519 requirements
These options allow the panel to be tailored to site‑specific needs.
Customization
ESP panels can be customized to match operational requirements, site standards, or integration needs. Whether the application requires full‑voltage control, variable‑speed operation, enhanced filtering, or additional field interfaces, Control Innovations can supply a complete package built for oilfield environments
