Dry Arc Resistance Tester Supplier

Dry Arc Resistance Tester is designed to conduct high voltage, low current arc Resistance test on solid electrical insulation material as per :

• ASTM standard D495-99 (2004)-Standard Test method for High - Voltage / Low -Current, Dry Arc Resistance of solid Electrical Insulation"
• UL 746A ”Testing for electrical properties." This product Is meant for all Insulator/ polymer/ electro plastic manufacturers and appliance manufacturers that use insulators in their products.

Why Arc Resistance Test ?
Many Cases of insulator failure are due to deterioration of Its surface because of sustained electrical discharge or Arc. Thls test method Is intended to test the resistance of insulating material when a high -Voltage low -current Arc close to the surface of Insulation, Intending to form a conducting path therein or in causing the material to become conducting due to decomposition and erosion.

Advantages
This Test ensures that our products meet high standards of quality & safety. This product is meant for all Switchgears/insulator/Polymer/electro plastic manufacturers and manufacturers who use insulators In their products e.g. Wiring Accessories, Appliances, HT/LT line insulators etc.

Description of the Test :

This test Is useful 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 An Arc is generated between these electrodes. The test consists of 7 Cycles starting from cycle 1. As the cycles progress the test become. progressively severe. The test specimen that have lower insulating strength fall 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 STRENGTHS (time In seconds) of various insulating materials. The test specimen may fall by forming a conducting path, by burning Into flames, by melting or any other physical, visual deformities.

Test Cycles :

• The unit is programmed to operate in 7 cycles according to ASTM Standard D495-99 (2004). Each cycle will be for duration of 60 seconds.
• These cycles are programmed to automatically change to the next cycle after the current cycle duration is completed. At the end of the last cycle the system automatically stops and the entire test results can be read on a LCD Display Meter.
