ESP failures are not just maintenance issues. A motor burnout or pump sanding after an unexpected trip directly translates into lost production and revenue.
The Medium voltage industrial drive AT27 ED ESP is adapted for pumps and engineered to protect them. Here is why the AT27 ED is the perfect surface companion for your submersible assets:
1. Protect Your Insulation (No Output Filter Needed)
Long power cables in deep wells act as capacitors, creating voltage spikes that can destroy motor insulation.
- The Problem: Standard VFDs produce high dV/dt, requiring bulky, expensive external sine-wave filters to protect the downhole motor.
- The AT27 ED ESP Solution: With its multi-level PWM technology, the AT27 ED ESP delivers a pure sine wave directly to the wellhead.
- The Result: You get extended motor life and reduced stress on cable insulation without the footprint or cost of external filters.
2. Zero Downtime with HOpCoD™
In high-solids or sandy wells, stopping the pump often means sanding it up. You cannot afford a trip just because a drive component needs maintenance.
- The Tech: Triol’s exclusive HOpCoD™ (High-Operated Commutation Device) bypasses failed power cells in less than 4 milliseconds.
- The Benefit: If a cell fails, the drive doesn't trip. It bypasses the fault and keeps your ESP running, preventing deferred production and protecting the pump from solids settling.
3. Universal Motor Control (Induction & PMM)
As fields mature, your lift strategy might change. The AT27 ED is ready for any downhole technology.
- It provides precise vector control for standard Asynchronous Induction Motors and high-efficiency Permanent Magnet Motors (PMM).
- Includes "Catch on the fly" technology to safely restart backspinning pumps, preventing shaft breakage during fluid fallback.
4. Grid-Friendly on Remote Fields
ESP wells are often located at the end of long distribution lines or powered by generators, where power quality is poor.
- The AT27 ED ESP features a built-in phase-shifting transformer that ensures IEEE 519 compliance with a power factor of ≥ 0.96. This protects your surface transformers and generators from overheating due to harmonics.
5. Fits in Any VFD House
Space is money, especially on offshore platforms or compact well pads.
- The AT27 ED ESP offers one of the smallest footprints in the industry with** one-sided service access**, allowing you to install it flush against a wall to maximize space in your control room or VSD container.
Stop compromising on run life. Choose the drive that protects your downhole investment.
