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.
SCR ELEKTRONIKS focuses on designing a solution around the end use at her customer. Instead of offering a standard instrument for a specific task, we have an approach of customizing the test bench to target the specific goals of the process or test procedure. Our measurement instruments, test modules, electrical power systems & software libraries are developed with this vision, thereby reducing the test system’s time-to-deploy.
It provides a Constant Current Source. The range and the test current can be set depending upon the range of the MCB. The Tripping time is indicated on Digital Time Interval Meter which stores the information till we reset the system.
Provision is also made in this panel to carry out demonstration of Instanteneous Operation of Short Circuit Protection.
