Specification of dissolved gas analysis of transformer oil

Description of dissolved gas analysis of transformer oil in U.S. Virgin Islands

Faced with increasing pressure to continuously improve network availability and reliability, asset owners are now often looking for increased coverage on their important transformers. Continuously monitoring the transformer’s main components (active part, bushings, tap changer, cooling system) is key to maximizing transformer availability, reliability and performance while reducing the life-cycle cost. Asset owners are therefore expanding beyond Dissolved Gas Analysis (DGA) and connecting to or adding more sensors to extend their online monitoring reach.

GE’s MS 3000 holistic and modular transformer monitoring system enables essential to comprehensive coverage of the most common causes of failure. It lets you combine the outputs of available sensors to form a homogeneous data flow coming from a single source. It uses analysis and sophisticated models to prevent data overload and deliver an aggregate view of the health of the transformer’s main components, providing intelligent alarms, diagnostics and suggested operational next steps. The MS 3000 is an “Expert System” which helps you confidently assess a transformer’s condition and optimize its operation and maintenance.

 

Key Benefits

• Continuous supervision of the whole transformer, integrating data from available sensors.
• Modular: essential through to comprehensive coverage of transformer failure modes.
• All information available at a glance, even across several substation transformers. 
• An “Expert System” to help you assess and manage your costly assets.
• Optimum operation efficiency with reduced life-cycle cost.
• Web server HMI, no need for software to access the data analysis
• Integration with GE’s Perception software for centralised information and leveraging of fleet data** .
• Easy inter-operability of the transformer with the Smart Grid / Digital Substation.

Applications

While more specifically aimed at transformer assets where the loss of availability has severe consequences for the network, the MS 3000 benefits from a highly flexible and modular design enabling it to adapt to a wide range of customer demands and types of applications:

• Suitable for most transformer types and ratings, independent of manufacturer
• Applicable to new and existing transformers
• Used in power generation, transmission and distribution
• Special solutions for HVDC applications
• Ideal for industries with process interruption risks

Expert System

Algorithms for analyzing the data acquired online are implemented in the software and reflect GE’s extensive experience with transformers.The expert system highlights issues through configurable alarms and provides clear correlated information as well as recommendations concerning the transformer continued operation, the suggested “next steps” and the need for services and maintenance.

Oil Analysis

Both off-line and online data can be analysed.DGA using the most common diagnostic tools: Duval’s triangle, Rogers and Doernenburg ratios, Key Gas methods, etc… as per IEEE C57.104 and IEC 60599. Users can select the method most appropriate to their situation. They can also perform Furfural determination and oil condition evaluation according to IEC 60422:

Partial Discharge

• Electrical PD.
• UHF PD.

Simulator

The built-in simulator module allows the user to simulate external events or internal transformer events and to study the corresponding effect on the transformer’s behavior. It can be invaluable for weighing up options when faced with a difficult decision but can also be used for training of personnel.

Report Generator

The configurable report generator quickly and easily creates a user-friendly report onthe status of the transformer and of its main components. The report can be created on demand for selected monitored functions over a specified time frame.

RModular monitoring solution for power transformers

The MS 3000 is a globally recognized online monitoring solution with well over 1,000 installations worldwide which benefits from extensive transformer manufacturing DNA. It is a powerful tool that concentrates most of the transformer data available and combines it with sophisticated models, diagnostic algorithms and practical experience to help the user evaluate the health of the transformer, monitor its current performance and optimize its operational efficiency. The MS 3000 is modular and highly configurable so that it can accommodate a wide range of specifications or customer requirements surrounding monitoring of the 6 main areas responsible for the failure of power transformers. Standard configurations are also available to cover typical requirements. Its wide range of communication options facilitates connection to SCADA systems, data historians and Asset Performance Management (APM) systems. All this is provided by a single vendor with extensive transformer manufacturing and monitoring experience, which supports the customer from conception to deployment, ensures that the solution meets expectations and stands by it for the long term.

 

HMI

The Web server built into the MS 3000 provides web pages in several languages which can be accessed using a standard web browser. The key data overview screen will highlight any alarm and enable to drill down into more specific data. When part of a transformer fleet, integration with GE’s Perception software** enables centralized information, leveraging of fleet data and fleet health ranking.

Sophisticated Modelling

With a multitude of sensors constantly delivering refreshed online data, the MS 3000 uses sophisticated models to analyse all this data, correlate it when additional sources are available and convert the data into actionable information in order to enable the asset owner to get the most out of the transformer.

Why we supply dissolved gas analysis of transformer oil in U.S. Virgin Islands ?

The United States Virgin Islands,[note 2] officially the Virgin Islands of the United States, are a group of Caribbean islands and an unincorporated and organized territory of the United States.[7] The islands are geographically part of the Virgin Islands archipelago and are located in the Leeward Islands of the Lesser Antilles to the east of Puerto Rico and west of the British Virgin Islands.[8]

The U.S. Virgin Islands consist of the main islands of Saint Croix, Saint John, and Saint Thomas and 50 other surrounding minor islands and cays.[9] The total land area of the territory is 133.73 square miles (346.36 km2).[7] The territory’s capital is Charlotte Amalie on the island of St. Thomas.

Previously known as the Danish West Indies of the Kingdom of Denmark–Norway (from 1754 to 1814) and the independent Kingdom of Denmark (from 1814 to 1917), they were sold to the United States by Denmark for $25,000,000 in the 1917 Treaty of the Danish West Indies[7] and have since been an organized, unincorporated United States territory. The U.S. Virgin Islands are organized under the 1954 Revised Organic Act of the Virgin Islands and have since held five constitutional conventions. Residents of the United States Virgin Islands are politically disenfranchised, having no representation in the United States congress.
