FixStar Fixed Speed Drives
ESP System Protection in a Fixed Speed Application
The FixStar family provides electrical submersible pump (ESP) operators with electrical system protection for downhole ESP systems in a fixed-speed application. It also provides an effective platform for analyzing well and pump performance in real time.
Proven protection system for ESP
The modular FixStar drive is a proven protection system for an ESP operating in a fixed-speed application. It incorporates a combination of a fused main disconnect switch (or circuit breaker) with a vacuum (or air-break) contactor that connects ESP systems to the surface power supply. This provides maximum protection for the ESP system in case of major surface or downhole electrical system faults. Built-in lightning arresters protect the downhole pump system from spikes in the supply system caused by lightning strikes. The UniConn controller in the FixStar drive provides extensive electrical system monitoring and protection against both surface and downhole electrical faults.
