Transformer Monitoring

Transformers are crucial for failure-free and stabilized operation of power transmission and distribution. Transformer failures or disruptions can result in costly power outages or even in the total loss of expensive plant assets. Moreover, transformers are the most cost intensive single component asset in high-voltage power transmission and should therefore be supervised with special care. MTE offers a broad range of products and solutions for the online gas-in-oil monitoring of transformers (online DGA). With its individual and modular system components MTE provides the optimal customer oriented solution for utilities, industries and transformer manufacturers.

  • Early Warning

    Composite or individual analysis of the key fault gases dissolved in power transformer oil for early warning indication and initial fault classification.

  • Intensive Care

    Permanently installed online DGA (Dissolved Gas Analysis) devices for the individual analysis of multiple gases and detailed fault classification.

  • Portable DGA

    This portable device analyzes dissolved and free gases from the isolation fluid of oil-filled power transformers and other electrical equipment.

  • HYDROCAL genX

    The new HYDROCAL genX product family is the first truly maintenance-free multigas online DGA (Dissolved Gas Analysis) solution combining proven near infrared (NIR) measuring technology with vacuum-protected membrane extraction.

  • HYDROCAL Offshore

    The HYDROCAL Offshore transformer monitoring systems are specially designed for the harsh conditions (salt water, corrosion) on offshore platforms (e.g. wind mill parks). Special painted housing with no window and the application of chrome nickel and stainless steel ensures the reliability and the persistence of the device.

  • Bushing & PD Monitoring

    Bushings or the line output represent the second largest group of transformer failures after windings and before tap changers. Therefore, bushing monitoring can help reduce these errors, while UHF partial discharge analysis of the active part of a power transformer is an ideal combination with online DGA from the HYDROCAL product family.

  • External Sensors

    HYDROCAL DTM is an innovative modular online monitoring system designed for power and distribution transformers. By correlating data from these various sources, the system enables early fault detection and prevents costly outages. 

  • Software

    HydroSOFT Hybrid App is a program compatible with MS Windows for controlling the eintire MTE HYDROCAL product line and reading out all types of relevant data.
