Artesis e-PCM for Gas Turbines: GTG Monitoring for Power and Oil & Gas
CCGT, cogeneration and remote oil & gas sites: how e-PCM monitors the gas turbine and generator from generator output — bearings, misalignment, windings without shaft sensors.
A gas turbine drives CCGT blocks, cogeneration and autonomous power at oil & gas sites. Bearing failure, misalignment or generator winding damage stops generation and process heat — GT overhauls mean weeks of downtime.
Many sites already run Bently Nevada CMS, but generator electrical faults and remote units without full CMS remain gaps.
Artesis e-PCM reads generator output current and voltage to detect turbine, coupling and gearbox mechanical issues plus winding degradation — panel install only, no GT shaft sensors.
Where it applies
| Segment | Unit | Goal |
|---|---|---|
| CCGT / power | 20–400 MW GTG | Block availability |
| Cogeneration | Refinery / metals CHP | Continuous output |
| Oil & gas | Field GT sets, compressor stations | Remote monitoring |
| Peaking / reserve | GT on thermal plant | Fewer forced trips |

What e-PCM monitors
Gas turbine
Rotor imbalance, GT–coupling–generator misalignment, bearing wear, looseness, reduction-gear issues.
Generator
Winding degradation, eccentricity, phase unbalance, harmonics, excitation clues.
GT auxiliaries
Lube/fuel pumps, cooling fans → e-MCM at MCC.
e-PCM vs vibration
| CMS/Bently | e-PCM | |
|---|---|---|
| High-speed GT | Industry standard | Complement |
| Generator electrical | Weak | Full |
| Remote site, no CMS | Expensive project | Fast retrofit |
| Install | Bearing probes | Generator panel |
Large CCGT: existing GT vibration + e-PCM on generator. Remote field GT: e-PCM as primary channel + Artesis IoT.
Oil & gas specifics
- Costly specialist visits — trending in SCADA matters
- Start/stop and part-load cycles — multi-band models
- Hazardous areas — ESA in safe switchgear only
- BOP compressors/pumps → e-MCM — compressors ESA
Architecture
GT → generator output → CTs + voltage → e-PCM → DCS / Artesis IoT
Typical cogeneration scenario
- GT vibration OK — planned outage in 3 months.
- e-PCM trends generator bearing and misalignment for 5 weeks.
- 36 h window — alignment and DE bearing change.
- Avoided process trip from lost power and steam.

Summary
Artesis e-PCM bridges GT and generator — especially on remote oil & gas sites and as the electrical layer on large CCGT with existing vibration CMS.
