Benefiting from decades of transformer manufacturing experience and previous transformer monitoring systems (MS 2000), GE now offers the MS 3000 online condition monitoring and expert system.
The MS 3000 system provides a holistic approach that not only relies on a GE’s Dissolved Gas Analysis (DGA) monitor but expands the monitoring by connecting to the other existing transformer sensors and adding functionalities and measuring devices as per customer requirements.
It is a modular system that can cover the active part of the transformer but also the bushings, the cooling system, the on-load tap-changer and detect transient over voltages and the presence of partial discharge. It gathers all this data, detects any worrying trend and cross correlates the information to confirm the diagnostic and helps you assess your transformer’s health.
The MS 3000 includes a user-friendly web-based interface. It computes mathematical models based on IEEE/IEC standards to deliver valuable operational information and has a build-in simulator and an expert system software that provides operational recommendations in case of alarms. All this information is available remotely through a wide range of communication methods and protocols (including IEC 61850).
The MS 3000 is an “all-in-one” monitoring solution ideally suited to critical transformers, when enhanced coverage of potential causes of failure is required to provide peace of mind.
Bushing Monitoring and Partial Discharge Detection for Transformers
Bushings account for a large proportion of High Voltage (HV) substation failures, often causing severe and costly damages. Preventive maintenance, early replacement and regular off-line testing have been employed to address this issue in the past. Now, technology exists that enables asset owners to detect impending failures and reduce their maintenance costs.
GE’s advanced Intellix™ BMT 330 is an on-line system that continuously monitors the condition of the bushings and can also detect developing partial discharge (PD) activity in the transformer main tank. It will alert personnel of fault conditions at an early stage and provide vital health information on the bushings and the transformer.
The Intellix BMT 330 can be utilized as a standalone system to monitor bushing insulation and partial discharge activity, or as an integrated, one-sourced solution with GE’s Kelman TRANSFIX Dissolved Gas Analysis (DGA) multigas analyzer and Perception Fleet software to provide a more in-depth view of the transformer’s condition and root cause of major transformer failures.

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.
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:

From the only vendor with 15 years PAS experience and installed base of >15.000 units
Dissolved Gas Analysis (DGA) and moisture measurements of insulating fluids are recognized as the most important tests for condition assessment of transformers. In previous years, multi-gas DGA was traditionally confined to a laboratory environment, with infrequent yearly off-line manual sampling aiding time-based maintenance strategies
However, as the global average age of transformers continued to rise, the possibility of rapid aging and even catastrophic failure between off-line tests also increased, leading many asset owners to adopt on-line DGA monitoring to provides remote alert and multi-gas diagnostic of deteriorating transformer condition.
This facilitated operational decisions without needing to go to site for manual oil sampling. It avoided unplanned outages, increased network reliability and enabled the move to condition-based maintenance.
In the early 2000’s, GE’s original Kelman™ range of on-line multi-gas DGA analyzers brought Photo-Acoustic Spectroscopy (PAS) measurement technology to the market. GE is now proud to introduce the Kelman DGA 900. its next-generation multi-gas on-line DGA and moisture analyzer. At its heart lies an evolved implementation of GE’s proven PAS technology, providing laboratory challenging levels of precision and repeatability with no consumables (carrier or calibration gases) and no need for frequent re-calibration. It also has enhanced computing power and scalable I/Os for future proofing and adding functionalities to grow each analyzer into a flexible transformer monitoring solution.
Transformer issues can now be detected in their infancy, making sure that they are fixed early so that the nominal expected life of the transformer can be achieved. Maintenance interventions can now be planned, reducing their length and their cost and causing less disruption to the network and customers. In addition, aging asset replacement strategies can be anchored on hard health condition data and not purely based on the age of the transformer.
The Kelman™ DGA 900 is an 9-gas on-line transformer DGA monitoring unit. Using our 4th generation of advanced photo-acoustic detection technology, the DGA 900 measures all significant fault gases (in ppm) as outlined by international standards as well as moisture in oil (%RH & ppm). The measurement of these gases allows the user to detect and diagnose a complete range of transformer faults.
