Gas Station

 

The E/One Gas Station is a modular approach that combines monitoring and control systems onto a single skid, customized to meet specific power plant requirements and budgets.

Gas Station modules include:

  • Main gas supply manifold and associated controls
  • Gas purity monitoring
  • Overheat monitoring
  • Dew point monitoring
  • Gas drying
  • Partial discharge monitoring
  • Seal oil system monitoring and control
  • Customized annunciator panels

Power utilities and independent power producers are increasingly concerned with upfront capital expenditures and subsequent on-site engineering and installation costs. They also require accurate, real-time monitoring information so that generator efficiency and generator performance can be maximized — and downtime minimized. The E/One Gas Station addresses each of these concerns and allows power plant operators, together with E/One, to configure targeted solutions for original equipment supply and retrofit applications.

Gas Station Features and Benefits

E/One Gas Station is a modular monitoring and control system that can be customized to fit the needs of a power plant

  • Flexible, cost-efficient approach to gas monitoring and control systems for electric power generators
  • Modularity couples technology and reduced installation and on-site engineering costs
  • Customized to meet specific needs and budgets
  • Hazardous area designs — compliance with national and international requirements

 

GGA/AUX 2-Mod Gas Station 

E/One's GGA/AUX Gas Station combines continuous gas purity monitoring with site-specific annunciation and auxiliary monitoring. E/One has optimized the auxiliary features to  offer an economical, fast lead-time solution to the unique requirements of any power plant. This GAS Station incorporates international requirements for hazardous area locations and is available in an open-frame or NEMA 3R configuration.

Gas Station Modules

Generator Auxiliary System module for E/One Gas Station displays critical gas supply, case, and differential pressures Generator Auxiliary System (GAS)
Used in conjunction with E/One's main gas supply manifold, provides local display of critical gas supply pressures, case, and differential pressure. May be supplied with digital displays in place of gages.
Generator Gas Analyzer for E/One Gas Station monitors hydrogen purity Generator Gas Analyzer (GGA)
Provides continuous monitoring of hydrogen and purge gases for efficiency and safety.
Generator Condition Monitor - Explosion-Proof Design provides early warning of generator hotspots Generator Condition Monitor (GCM-X)
Provides early warning of generator hotspots, which can lead to catastrophic failure.
Generator Gas Dryer (GGD) from E/One removes moisture from generator cooling gas, reducing possibility of corrosion in electric power generators Generator Gas Dryer (GGD)
Removes moisture and contaminants from generator cooling gas, reducing threats of corrosion and windage losses.
Auxiliary System for E/One Gas Station can monitor the generator's seal oil system or other requirements for the generator Auxiliary Systems (AUX)
Customized to meet specific requirements and often include seal oil system monitoring and site-specific annunciator displays.
Two-module Gas Station from E/One combines the Generator Gas Analyzer (GGA) with the Generator Condition Monitor - Explosion-Proof Design (GCM-X) GGA and GCM-X Dual-Module Gas Station
The popular two-module GGA/GCM-X Gas Station combines continuous gas purity monitoring of the Generator Gas Analyzer with early warning of overheat monitoring of the Generator Condition Monitor. The two-module Gas Station is an ideal retrofit configuration in support of generator life extension.
