This is a hybrid 3 station-bench to test MCCB thermal tripping characteristics as per IEC 60947-2 cl 6.3.3 and custom based requirements at a controlled temperature (that can be set) adding another compliance parameter to the list. The speciality of this test system is its in built heater allowing the user to conduct the test at any desired temperature.
Flexibility to the user for time, current and temperature settings for testing as per IEC as well as customized parameters.
Drop down menu in the software to once select the type (rating or calibre) of MCCB: Rest of the test parameters get selected automatically (User can simply jump from one type of MCCB to other instantaneously)
IEC based test parameters automatically configured + The user can set its own parameters in the system for his / her research and development activities.
Software: NI LabVIEW based for user interface, settings selection, process control & report generation
Servo Controlled Voltage Regulation ensures stable voltage at the output.
In built micro controller based timer to set time current cycle.
In built timers per station to display test and trip time.
Test results are displayed on monitor and stored against serial number or a bar code.
Generation of Reports in MS Excel format or to Print.
Exact trip current wave-form (and not a vague band) is displayed on PC.
Two or more curves can be compared on PC.
440 V, 3 phase, 50 Hz input.
In built thermal heating chamber of dimensions depending upon the MCCB rating.
Output current programmable up to 800 A continuous (customizable).
Can test MCCBs of different ratings up to 250 A.
Test Procedure options: IEC 60947-2 / customized
Pressure Required for pneumatic handling: Approximately 8-12 Bar depending on the MCCB size.
PC provided: IBM PC / compatible make with NI LabVIEW based Testware TM.
500 VA branded UPS.
The system can be customized w r t the current source rating, the number of temperature channels, whether the system has to be supplied with isolation amplifiers or otherwise, etc.
The system is mainly used to plot / determine the MCCB thermal trip characteristics in a high / low temperature environment. The system may be supplied with a test chamber which maintains temperature, humidity. More MCCBs (of different makes) can be compared simultaneously for tripping performance.
