Descripción del producto

The Calmet TB*0 Four Position Meter  Test Bench is used for calibration and testing of single and three phase electromechanical and electronic active and reactive electricity meters and portable test equipment.

The TB*0 Test Bench comprises:

• three phase voltage and current power source with internal reference 0.*5 accuracy class. Three phase power source generates voltage up to **0V and current up to **0A with programmable shapes, frequency in *0…**0Hz range and phase shifts in 0…±**0° range,
• four position testing stand with photo scanning heads and cables,
• eight s multiplexer for received impulses from scanning heads,
• PC with Mpx8 PC software and Calpro **0 software.

The TB*0 Test Bench, using Mpx8 PC software, performs the following automatic and simultaneous tests of 4 electricity meters:

• measure the basic error characteristics and repeatability,
• checking the starting current,
• checking the no-load run,
• measure the influence of frequency, voltage, self-heating, distortion and special shapes of currents and voltages, reversed phase sequence,
• checking the impulse output and energy meter counter,
• checking the maximum power indicator.

The TB*0 Test Bench, using Calpro **0 software, enables additionally to test the following devices:

• protection relays,
• current transformers,
• current clamps,
• measurement transducers,
• Power Quality measurement devices.

The TB*0 Test Bench employs modern precision power source with internal reference without need to use additional external reference energy meter with additional cables. By this conception of the TB*0 Test Bench may be achieved simultaneously extremely compact size, light weight, high metrological properties at reasonable price.

The TB*0 Test Bench is controlled by means of personal computer with installed Mpx8 PC software and Calpro **0 software in Windows operating system.
