The circuit breaker is secured to the vertical board in such a way that the distance of horizontal axis of the sample is 180 mm from the platform the vertical board being in, so fixed that the distance of the mounting surface is 200 mm from the hinge.
On the surface, opposite the mounting surface of the circuit breaker, a supplement mass is fixed so that the static force on the metal stop – plate is 25 N in order to ensure that the moment of inertia of the complete system is substantially constant.
The test setup is require for Short Time Over current Test, Fault Current Making Capacity Test and Short Circuit current Carrying Capacity test on Prepaid Energy Meter as per IS 15884
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.
SCR ELEKTRONIKS have developed “TEMPERATURE RISE TEST BENCH FOR MEDIUM VOLTAGE SWITCH BOARDS” to measure rise in temperature at various points as mentioned in standard at junctions.
The set-up consists of a True RMS Constant Current Source (to maintain the Current within + / – 1 % of set value with Digital Indication), PC based control system, Temperature data logging on PC, Servo-Controller and other indications. Digital voltmeter Primary Voltage) indicates the position of auto transformer (variac).
SCR ELEKTRONIKS have developed “PC BASED TEMPERATURE RISE TEST BENCH 25kA” to measure rise in temperature at various points as mentioned in standard at junctions. The set-up consists of a True RMS Constant Current Source (to maintain the Current within + / – 1 % of set value with Digital Indication), PC based control system, Temperature data logging on PC, Servo-Controller and other indications. Digital voltmeter Primary Voltage indicates the position of auto transformer (variac).
Servo controlled mechanism is used to maintain constant current throughout the test in manual mode. CR/AL(‘K’ type) type thermocouples are used for temperature sensing.
