Introduction:
High voltage arc tracking rate tester (HVTR) is strictly designed and manufactured according to UL746A standard,it use high-voltage,low-current arc to formation carbonization on the material surface to test material high-voltage arc influence degree.
HVTR tester electrodes sizes are designed according to standard requirements.It arc continuously two minutes on sample surface in particular current (2.36mA) to test sample high-voltage arc carbonization capability in schedule time. HVTR tester use high power and voltage transformer,high voltage current limiting resistor and with a high precision voltage acquisition system to generate high voltage arc.
