High Voltage Tester for testing Dielectric Breakdown Tes
SCR is a pioneer in Electrical Safety Test Equipment since its inception in 1975. We make an impressive range of customised electrical safety test equipment as per IEC 60335 & other standards. This product is a Customised High Voltage Tester for testing Dielectric Breakdown Voltage and Dielectric Strength of Solid Insulating material as per ASTM D149 – 09.
In this test, an AC voltage at the frequency of the electrical utility is applied using simple test electrodes at opposite faces of the solid insulating material. The voltage is gradually increased in steps as described in clause 12 of ASTM D149 – 09.
The SCR High Voltage model, HvMax – Automatic is custom built for this test. It has the necessary system to support High Voltage Application up to 100kV AC. Safety Interlocks & features such as foot switch etc. are provided to take care of operator safety. The high voltage, steps and other parameters can be programmed in the dedicated control unit. The operator gets record of the voltage & test as it progresses. We have a PC based option on the HvMax like in all electrical safety test equipment from us. The test routines are pre-programmed to support ASTM D149 – 09 so there is no room for operator error. This equipment can be used as a generic High Voltage tester since all the parameters are programmable using the PLC & timer.
Many manufacturers with factories in India such as Philips tests 100% of their production on SCR ELEKTRONIKS Electrical Safety Test Equipment & High Voltage Testers.

High-Current Arc Ignition Test Machine
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.

Hot wire ignition Apparatus
The SCR ELEKTRONIKS Heated Wire Tester is used for testing Ignition of Materials by Hot Wire Sources as per ASTM D 3874. As suggested by the standard, Heated Wire Tester is designed to evaluate a material’s ability to resist ignition when exposed to abnormally high temperatures.
As per the standard, the center position of the specimen is wrapped with a Nichrome wire in a specific way as per clause 10.1 of ASTM D 3874. The free ends of the wire is connected to a circuit which supplies current as per clause 6.3 “Supply Circuit” of ASTM D 3874. Next the circuit is energized such that it dissipates 0.26 W/mm. When the ignition occurs or after 120 seconds (whichever is earlier), the circuit is switched off and the time to ignition is noted. If the material under test melts, then the circuit is switched off when the material is no longer in touch with the 5 turns of the heated wire. In such case the time to melt is noted.
UL 746A refers to ASTM 3874 – 88 for this hot wire ignition test. As per UL 746 A, for a given material, the Hot Wire Ignition Performance Level Category (PLC) is to be assigned based on the determined mean time for ignition (IT). Please refer to table 31.1 of UL 746A.
Like-wise for all other standards such as IEC 60947 – 1 and IEC 60695 – 2 – 20 (Fire hazard testing – Part 2: Glowing / Hot wire based test methods – Section 20: Hot-wire coil ignitability test on materials) the testing method is same.
The SCR ELEKTRONIKS Heated wire test apparatus has a micro-controller based dedicated logic unit to conduct this test. It’s built in extruded aluminium chassis with all material carefully chosen for durability & dependability. It’s used by leading test labs world-wide.
