Data Processing Software TEGRAF and LOGA

Characteristic

TES has developed a special software intended for further analysis of data acquired during measuring and testing of NPP equipment. Softwares TEGRAF and LOGA make for displaying of time behaviour of analogue or binary parmeters and mathematical processing of the parameter values acquired in the form of data files.

TEGRAF software

is used for processing of data acquired by analogue modules of the MOSAD®-6, MOSAD©-5 a MOSAD®-4 System or by the Mobile Testing Unit (MMU). It can also be used for processing of data stored in text files obtained from other sources.

Characteristics

• Simultaneous reading and processing of up to 128 parameters.
• Display of time behaviour of selected parameters in a chart relating the parameters to a selected coordinate axis.
• Selection of an interesting time interval and its detailed displaying (zoom).
• Search for local extremes, determining their values and entering them into the chart.
• Interpolation of the parameter time behaviour using a polynomial.
• Creation of a wave envelope.
• Mathematical operations between values of different parameters at a given time.
• Calculation of average and root-mean-square values of the processed parameters.
• Calculation of derived parameters (phase shift, power factor, frequency , electrical power, impedance, harmonic components of periodical parameters – FFT, etc.).
• Inserting of titles and legends.
• Printing and storing of the complete charts.

LOGA software

is used for processing of data acquired by the binary modules of the MOSAD®-6, MOSAD®-5 and MOSAD®-4 System and by the MFV-6 Logic State Monitors or by the HRN-5 Overvoltage Recorder. If combined with an appropriate converter, it can also be used for processing of data obtained from other sources.

Characteristics

Tools for creation and fine-tuning of equipment functional model in the form of logical schemes.
Automatic evaluation of the acquired data (real equipment behaviour) in comparison with the equipment model (expected behaviour).
Displaying of the acquired data in the form of charts.
Selection of interesting time intervals and their detailed displaying (zoom)
Computational analysis of the length of time interval
Printing of reports and charts of parameter time courses
