Surge Tester is intended for testing of insulating materials, and for testing of particular components in mains operated electronic apparatus for household and telecommunication. This is tested with high voltage surges 10kV.

High voltage switch with IEC 60065 circuit is located in solid, isolated housing made of Plexiglas, so that it is protected from dust. Due to the transparency monitoring of high voltage switch is possible. The switch is mounted on top of sheet steel housing that consists control unit and high voltage source.

The arrangement of switch electrode is as shown figure 5b of IEC 60065. Brass sphere and contacts of high voltage switch are gold plated to avoid oxidation.

2.Auto/Manual selector switch-  In Auto mode Timer will conduct all the operations.  In manual mode seperate push buttons will be provided for making ON/OFF the tests.

3. Start, Stop, Reset, Emergency OFF Push Buttons will be provided seperately

4.Output will be on Clip ON terminals with appropriate ratings.

5. Automatic switching of the test parameters will be through contactors.

6.Panel will be built in M.S. Powder Coated cabinet floor mounting type.

SCR ELEKTRONIKS focuses on designing a solution around the end use at her customer. Instead of offering a standard instrument for a specific task, we have an approach of customizing the test bench to target the specific goals of the process or test procedure. Our measurement instruments, test modules, electrical power systems & software libraries are developed with this vision, thereby reducing the test system’s time-to-deploy.

The Ball Pressure Test Apparatus is used to check the integrity of dielectric material with respect to resistance to elevated operating temperature. The Ball Pressure Test Apparatus model BP 21 takes care of this testing useful for insulator manufacturers and other electro-technical manufacturers who use insulating material in their electrical appliances. The BP21 is made of stainless steel for long life.

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 test method as per ‘ASTM D 495 – Standard Test Method for High-voltage, Low-current Dry Arc Resistance of Solid Insulating Material’ is pre-programmed in the PLC. Please refer to ASTM D 495 for more details. This equipment complies testing as per other standards as well, such as IEC 61621 (Dry, solid insulating materials - Resistance test to high-voltage, low-current arc discharges), UL 746 A (Polymeric Materials – Short Term Property Evaluations Testing For Electrical Properties) and IS 14672 (Method of Test for High Voltage Low Current Dry Arc Resistance of Solid Electrical Insulation).

High-Current Arc Ignition Test Machine is used for evaluating Ignition Performance Level Category as per UL 746A. Any insulating material should resist electrical arcing when a high current tries to make path between a short distance that is only ‘connected’ by insulating surface. This is a requirement as per IEC 60947 - 1, BS EN 60950 - 1 and IEC 60335 - 2 - 40. Thus, it is a basic electrical safety requirement for all components such as cables, or for that matter any device employing an insulation such as polymers or polycarbonates.

The SCR ELEKTRONIKS High-Current Arc Ignition Test Machine makes testing as per clause 32 of UL 746A a breeze. It offers a Siemens PLC based control system with all relevant meters on board. It is a cost-effective and yet elegant apparatus for your quality control department. Even the IEC 60947 - 1 clause 8.2.1.1.2 is available as a pre-programmed test procedure – something switchgear manufacturers have come to expect from us. The whole equipment is built in extruded aluminium with multiple fail-safety interlocks.

Safety Test Panel for Domestic Mixer with PC Datalogging. The tests are Performed as Prescribed in IS the Panel Carries out different tests one by one and provides indication of the Test results as OK or NOT-OK. It is very useful and handy in line testing on Mass production line as well as type Testing. Special fixture can be provided for the specific product. This avoids the connections & disconnections of the product for different tests. The total time for entire testing is less than 20 seconds. Micro controller based sequential timer maintains the sequence of operation and displays the test status. This manual contains information about operating instructions and maintenance of the equipment. Please go through this manual carefully and retain it for future reference.
