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.
