The Calmet TB10 Single Position Desktop 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 with accuracy referenced to an internal reference meter.
The Calmet TB10 Test Bench employs modern precision power source with the internal reference (without need to use an additional external reference energy meter with additional cables).By this conception may be achieved simultaneously flexible customer orientated solution characterised by extremely compact size, light weight, high metrological properties at reasonable price.
In case the high-accuracy application requirement, it is possible to upgrade the existing Calmet TB10 Test Bench by adding an external reference meter.
The Calmet TB10 Test Bench comprises:
• three phase power source with accuracy class of internal reference 0.02 or 0.05. Three phase power source
generates voltage up to 560V and current up to 120A with programmable shapes, frequency in 40…500Hz range and phase shifts in 0…360° range,
• single position testing stand with photo scanning head and cables,
• Calpro 300 Basic + TS (Test System) software.
The Calmet TB10 Test Bench performs the following automatic tests of 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, reversed phase sequence, distortion and special shapes of currents and voltages,
• checking the impulse output and energy meter counter,
• checking the maximum power indicator.
