metrological support

The system model of wireless technologies security was proposed on a level of the structure “system – signal – channel – tract” and its metrological support according to the conception “object – threat – defence”. The software of data encryption procedure for WiMAX systems based on AES standart and C# programming language was developed in limits of the created model.

In the article questions of error estimation of measuring voltage and current transformers used in electric energy metering systems are discussed. Dependencies of errors on values of real secondary burden of such transformers. Measuring device is recommended capable of measuring real secondary transformer burden
