Influence of Supply Voltage Test Equipment ‘ISVT 01’ is used to measure and analyze the influence of supply voltage on energy meter. This test is described in various standards for energy meters such as IS 13779, IEC 62053 etc.As per CEI / IEC 62053-21, IS 13779 clause 12.7.2: The test shall be carried out under the following conditions: 1. Meter in operating condition. 2. Voltage and auxiliary circuits energized with reference voltage. 3. Without any current in the current circuits.
The SCR Elektroniks Endurance Test Bench is designed for electrical and mechanical endurance MCB and RCCB as per clause 9.11 of IEC 60898-1. The source and the load is designed to comply as per the general test conditions specified in Cl 9.11.1. The accompanying pneumatic fixture is designed to hold custom built designs of MCB and RCCB while the microcontroller based timer unit can be configure to follow test procedure summarized in Cl 9.11.2.
The SCR Elektroniks MCB Instantaneous Trip Test Bench is designed for Testing of MCB to carry out “Test of Instantaneous Tripping and of correct opening of the Contacts” as per IEC: 60898-1:2002 Clause 9.10.2 at rated voltage. This test is carried out with power factor between 0.95 and 1 with the sequence operation being O-t-CO-t-CO-t-CO with timings as specified in 9.12.11.1.
The SCR Elektroniks 3 station MCB Temperature Rise and Power Loss Test Bench is economically designed to verify temperature rise and measure power loss as per clause 9.8 of IEC 60898 with the circuit designed to follow test procedure as per Cl 9.8.2. The temperature rise is measured in accordance with Cl 9.8.3 and 9.8.4 while power loss is measured and verified as per Table 15 of Cl 9.8.5.
This product is used by leading MCB manufacturers on their production floor to test and calibrate the thermal tripping time (upto 60 seconds) for 2.55*I_n.
The product can be customized as per the number of stations: 1 (stand alone), 2, 4, 6, 8, 10 and 12 stations. Additionally, the product can be microccontroller based with each microcontroller controlling an individual station, or a PC based wherein the PC controls all the stations simultaneosuly and independenly of each other. The product is available as a standalone module with micro controller based control – without the use of PC as a low cost alternative with features as scalability and accuracy intact.
This bench is built to test MCCB instantaneous tripping (also known as Short Circuit or Magnetic tripping) as per IEC 60947-2 Cl 8.3.3 and custom based requirements. A speciality of the system is that it includes differently designed systems for two different current ranges (Smaller range for currents < 2000 A and higher range for currents >2000 A) thus ensuring equal reliability, accuracy and regulation for both low current and higher current MCCBs. Specially designed custom built jigs are able to accommodate different types of MCCBs enabling the user to test all kinds of miniature circuit breakers on a single test bench. In addition, the system can be made such that it covers the entire range of MCCBs for production floors producing all ratings of MCCB.
