  • Input Supply Voltage 230 V +/- 10 %

  • Test Voltage 0 – 12.5 kV adjustable (max 15 kV)

  • Dedicated PLC system for control of sequence and user friendly

  • Weight: Approximately 140 kg

  • Approximate Dimensions: 900 mm width, 600 mm depth, 700 mm height

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

  • ASTM D 495-99 (2004) -“Standard Test method for High – Voltage / Low -Current, Dry Arc Resistance of solid Electrical Insulation”

  • UL 746 A “Testing for electrical properties.” This product is meant for all insulator/ polymer/ electro plastic manufacturers and appliance manufacturers that use insulators in their products.

The product is compact and can be mounted on a table. It comes with an inbuilt legacy microcontroller module to conduct the test sequence exactly as per the ASTM table. The program has the voltage and current calibration facility. In addition, the test voltage can be adjusted using a variable auto transformer for any value till 12.5 kV. The micro controller displays the fail result as to the number of seconds the sample has withstood or declares the sample as pass.

Other safety features include zero interlock facility and door open indication and control for user safety making the product a state of an art one.

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.
