Is used to measure and analyse the influence of short-time over currents on energy meter. This test is described in various standards for energy meters such as IEC 62053, IS 13779 and so on.
The STOC 01/02 briefly consists of a power circuit and a control panel. The power circuit feeds the ‘overcurrent’ to the UUT. The control panel provides the user interface to adjust the parameters as per the requirements of the standards and the UUT.
The Power circuit in the Short-time Overcurrent Test Equipment contains a variable voltage source that has capacity to source high current value for short time.
Short-time Overcurrent Test Equipment is used to measure and analyze the influence of short-time overcurrents on energy meter. This test is described in various standards for energy meters such as IEC 62053, IS 13779 etc.
As per CEI / IEC 62053, short-time overcurrents shall not damage the meter. The meter shall perform correctly when back to its initial working condition and the variation of error shall not exceed particular values specified on basis of the class of the energy meter.
