SCR ELEKTRONIKS have developed equipment namely“DC CONSTANT CURRENT SOURCE”. The system comprises of Constant Current Sources having ranges: 900A continues & 3000A short time at 8V maximum.
SCR ELEKTRONIKS have developed primary and secondary Current injection test trolley for Switchgear manufacturers for testing of ACB , MCB , MCCB. It is low Voltage high Current source with control circuitry, digital read out for test current and trip time measurement. We can select different links of CT range as per the required test Current.
SCR ELEKTRONIKS have developed SECONDARY CURRENT INJECTION TEST TROLLEY for Switchgear items, CT manufacturer and where three phase current application is called for. It is low Voltage, 3 phase Current source with control circuitry, digital read out for test current and trip time measurement. We can select different CT ranges for each phase independently and adjust the current as per the required test Current.
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.
