Efficiency allied to Simplicity and Usability

Sigma EAM offers features that meet all the needs of the assets management, maintenance engineering, and performance of maintenance of electric power carriers. Watch the video below or click here for more details.

Smart Grid and IoT

Allying the background of Treetech team with its pioneerism in the development of Intelligent Sensors and Online Monitoring, Diagnosis, and Prognostics software of the condition of high voltage equipment, the EAM was developed already incorporating the Smart Grid and IoT philosophies. This allows for a natural integration of the online monitoring sensors and systems with the routines of maintenance engineering and performance of field activities. Click here for more details.

Predictive Maintenance and Analytics

Sigma EAM definitively consolidates the migration procedure of Preventive maintenance to Predictive, based on the actual condition of the assets, instead of simple cycles of time or of counters. This is possible due to the native integration of the EAM to the online monitoring systems, especially Treetech’s Sigma ECM, which provides diagnosis and prognostics of the condition of the assets from engineering algorithms and data of sensors obtained in real time.

Specific tool of the electric sector

Sigma EAM is based on the entire know-how of Treetech in engineering of maintenance and reliability, specification, design, construction, testing, commissioning, operation, and online monitoring of assets. Thus, the EAM was specially designed to the needs of the electric sector, aiming at simultaneously meeting the needs of the specialized technical management and maximization of results, in perfect synergy with the activity of the power carriers, not being a generic solution, or adapted from other segments.

Treetech Differential

For over 25 years Treetech is a pioneer in the development Intelligent Sensors and GTD asset Online Monitoring, providing innovative, prize-winner solutions internationally and with several patents in Brazil and worldwide, seeking to keep the safety and continuity of the electric system, with more than 85,000 equipment units and 400 systems operating in 50 countries. With the Sigma EAM, the expertise of more than 35 years of technical and managerial performance of this multidisciplinary team in carriers and manufacturers of assets is now available to the Asset Management.

Modularity and Usability

Sigma EAM has a modular structure that is easily adjustable to the processes and flows of work of user companies, which simplify its initial implementation process. Its interface, 100% web-based, allows to simultaneously open several screens in parallel tabs and exempts the installation of specific software in the user computers. The expertise of simple, intuitive, and efficient use is complemented by the Mobile application, which allows the offline usage and posterior synchronization. Click here for more details.

Open Architecture

The philosophy of open architecture is a premise in all Treetech solutions, of sensors and online monitoring system to Sigma EAM. Thus, the EAM can be integrated with several types of systems, especially ERP’s, ONS systems, such as SAM (Maintenance Follow-up System), and Scada systems. This open architecture also allows the integration of proprietary applications of the user with full safety through webservices, guaranteeing the integrity of the EAM’ business rules.

Unification of data “silos”

Regardless of company size, it is common that the data are isolated in several “silos” such as dedicated software, electronic sheets, independent files, paper records, and others, which store such information with dispersion and that, if used with integration, would be crucial for the optimized management of processes:

    • Events of defects or non-compliances
    • Corrective maintenance records
    • History of preventive and predictive maintenances
    • Test results
    • Studies of the protective system
    • Adjustments of the protection relays
    • Settings of intelligent sensors
    • Diagnostics of online monitoring systems
    • Among others.

Sigma EAM solves this issue consistently by acting as a single source of data, gathering all key information in the same platform, which allows intelligently and efficiently automatizing the main procedures of maintenance engineering and management of assets, maximizing corporate outcomes.

The ideal tool for the intelligent and optimized management of assets

The natural complexity of the activities of generation, transmission and distribution of power, allied to the continuous pressures for greater reliability, cost reduction and better results makes it fundamental to resort to an intelligent system for asset management. This need becomes even more evident in the scenario of assets near the end of their useful life and loss of knowledge of the experts due to retirements or team reductions.

In this context, Sigma EAM is a complete tool, with all features necessary for an intelligent and optimized management of assets and the planning and control of performance of maintenances and use of material and human resources.
