Real-time thermal condition monitoring is an integral asset protection method used to avoid transformer outages by detecting future transformer faults. MTE has embraced this monitoring practise by developing the MS-7 HYDROCAL Thermal Monitoring Extension Package which is designed to acquire all pertinent data required for thermal analysis.

This innovative solution, which has been developed in cooperation with MR (Maschinenfabrik Reinhausen), measures 3 oil temperatures (top oil, bottom oil & tap changer oil), ambient temperature, load current, load voltage and the tap changer position. These measurements are centralised and passed over to its analogue outputs:

  • 7 analogue outputs 4 … 20 mA

The analogue outputs of HYDROCAL MS-7 are directly connectable to the analogue inputs of HYDROCAL 1003, 1004, 1005, 1008 or 1009 units and in conjunction with these units, it offers a complete transformer monitoring system in one package.
