An event is characterized by the change of state of one of the parameters that Transformer Fleet Management monitors. The change of state indicates that one of the alarm criteria has been exceeded, either at the alert level or at the critical level.

The edge (hardware) that is used in the TFM solution and connected to the transformer,is enabled for real-time data reading, but the data is sent to the platform in sampling form, because the number of data read is high. The frequency of data read can be configured by the user with a minimum period of one second, and this information is sent to the platform every five minutes.

The data update to the TFM platform is performed reliably, every five minutes, if a stable connection is ensured by the internet provider.

To use the mobile phone technologies on TFM hardware, it is necessary to contract plans with mobile data packages starting at 500 megabytes (MB) per month.

The WEG Industrial Transformer Scan hardware is factory adjusted, this process is done in the equipment to correct possible errors in the measurement.

The equipment calibrations can be done on a regular basis following your company's quality policies.
