GE Kelman DGA 900 PLUS 9 gas on-line DGA

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.

Benefiting from over 15 years of multigas DGA vendor experience and over 15.000 devices in the field,

the DGA 900 encapsulates learnings and improvements derived from its predecessors to bring improved performance,

innovative new features, enhanced user experience and increased field reliability and robustness.

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.

Subsystems 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 sub-station asset.

It is most suited for monitoring large, mission critical transformers or compromised transformers

with a view to extending their life and preventing any unexpected failure:
