Kelman DGA 900 PLUS
9 gas on-line DGA expandable with add-ons to a Transformer Monitoring System (TMS)
The Kelman DGA 900 PLUS is a member of the next generation of multi gas monitors. Built from the DGA 900 platform, the PLUS extends the monitoring capability beyond just DGA.
Knowledge of the condition of transformers is essential for all electrical networks and on-line monitoring of transformers is an increasingly vital component of successful asset management programs. The comprehensive information provided by the Kelman™ DGA 900 PLUS not only allows expensive failures to be avoided but enables asset capabilities to be maximized.
The Kelman DGA 900 PLUS builds on the standard 9 gas DGA and moisture capabilities of the DGA 900 by enabling the addition of extra sensors, electronic cards and firmware algorithms to expand its monitoring capabilities. Bushing monitoring, partial discharge detection, OLTC monitoring, transformer models are amongst the options available to offer an integrated system which delivers a more in-depth picture of the transformer’s overall condition and will monitor the root causes of most transformer failures.
Key Benefits Kelman DGA 900 PLUS:
- Modular and retrofittable architecture using selectable standard add-on cards
- Provides extensive remote insight into transformer condition and safe operation
- Enables correlation of data for validation and in-depth fault analysis
- Graphical presentation using built-in web-page based HMI and local color screen
- Full integration with GE’s acclaimed Perception™ Fleet asset management software
- From the only vendor with 15 years PAS experience and installed base of >15,000 units
Applications
While on-line DGA is now widely accepted as the most effective method of assessing the condition of a transformer, it does not cover all the possible sources of issues. Sub-systems like the tap changer, the cooling system or the bushings can generate their own problems if they are left unmonitored.
The DGA 900 PLUS monitoring system integrates DGA measurement, additional sensors, analysis models and data handling features to address the majority of prevalent failure modes. This cost-effective package provides the condition assessment tools essential for the effective management and optimal utilization of this critical substation asset.
