INSTRUCT Drive EFX fixed speed drives
Protect your ESP system from surface or downhole failure
The modular INSTRUCT Drive EFX fixed speed drives provide electrical system protection for downhole electrical submersible pump (ESP) systems in a fixed-speed application. They also provide an effective platform for analyzing well and pump performance in real time.
The INSTRUCT Drive EFX incorporate 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.
