Protection has assumed a large importance in the power industry in the recent years. This protection involves the use of relays on a large scale. Relays are basically used to give commands to circuit breakers, contactors, etc by sensing different parameters like current, voltage, etc. Just as electrical circuits may range from a few watts to 100 megawatts, the size and rating of the relays vary considerably. Study of relays is now being included in the engineering curriculum. M/S SCR Elektroniks have developed demonstration units for different types of relays such as under protection/over protection relay, temperature protection relay, motor protection relays, AC/DC relays and contactors keeping the engineering curriculum in view.
This equipment is made to test the electrical insulating material by exposing it to Arcing under high voltage. The test specimen is placed under electrodes, spaced at a distance of 6.35mm as per ASTM D 495. An Arc is generated between these electrodes. The test consists of 7 Cycles starting from cycle 1. As the cycles progress the test becomes progressively severe. The test specimen that has lower insulating strength fails earlier in the first few cycles while those with higher insulating strength sustain higher cycles. The test is halted when the specimen fails and the time taken from the start of the test till the failure is used for comparing INSULATING STRENGHTS (time in seconds) of various insulating materials. The test specimen may fail by forming a conducting path, by burning into flames, by melting or any other physical, visual deformities.
The Dynamic Mechanical Load Tester is suited for routine and high-level research applications due to its exceptional overall performance and user-friendly design. Simple operation is made possible by a software navigation guide and an intuitive sample clamping design.
The SCR Elektroniks 3 station Socket Endurance Test Bench is designed to verify the endurance testing of sockets as per IEC 60884, IS 1293 and BS 1363. Typical sockets ratings covered are for the entire range (typically 6 – 32 A) for both 3 phase and single phase loads. The tests included (that can be customized) are as follows:
1. Normal Operation (Referred to as Cl 21 in IEC 60884, Cl 21 in IS 1293 and Cl 18 in BS 1363)2. Making and Breaking Capacity (Referred to as Cl 20 in IEC 60884, Cl 20 in IS 1293 and Cl 17 in BS 1363)2. Making and Breaking Capacity (Referred to as Cl 20 in IEC 60884, Cl 20 in IS 1293 and Cl 17 in BS 1363)
The SCR Elektroniks 3 station Switch Endurance Test Bench is designed to verify the endurance testing of household and rocker switches as per IEC 60669, IS 3854 and BS EN 60669. Typical switch ratings covered are for the entire range (typically 6 – 45 A) for both 3 phase and single phase loads. The tests included (that can be customized) are as follows: 1. Normal Operation (Referred to as Cl 19.1 in IEC 60669, IS 3854 and BS EN 60669) 2. Making and Breaking Capacity (Referred to as Cl 18.1 in IEC 60669, IS 3854 and BS EN 60669) 3. Temperature Rise (Referred to as Cl 17 in IEC 60669, IS 3854 and BS EN 60669) 4. Fluorescent Lamp Load (Referred to as Cl 19.2 in IEC 60669, IS 3854 and BS EN 60669) 5. Tungsten Filament Lamp Load (Referred to as Cl 18.2 in IEC 60669, IS 3854 and BS EN 60669)
Solar panel manufacturers must be prepared to have panels evaluated and to rethink and re-evaluate products that may raise safety problems or fail fire-resistance testing to achieve full compliance under Solar PV Module Testing Equipments. Understand which rack systems and installations are compatible with your panel type after having it tested. The racking manufacturers are in the same boat. To ensure compatibility with PV panels, educate yourself with the products and new innovations in the mounting and roofing product industries.
