HV-Incline Plane and Erosion

High Voltage Inclined Plane Tracking and Erosion Test Equipment for Insulating Materials as per ASTM D2303

Lab Test

As per ASTM D2303, insulating material should withstand against tracking & Erosion on the field. Which why they are evaluated in a laboratory by means of liquid contamination in a particular arrangement. The equipment displayed herewith are used for the same purpose. A high voltage is applied between two electrodes and a liquid contaminant is used in between so as to check & measure tracking. We offer this system in various configurations based on your application – R&D or Compliance Test & Assessment. The routines/measurements that can be conducted by this equipment are:

  • Initial Tracking Voltage
  • Time to track
  • Erosion

In Initial Tracking Voltage test, as per clause 9.0 of ASTM D2303, test voltage is applied to the electrodes and is gradually increased in steps till the insulation fails.

A qualified operator observes & records the character of the track and the appearance of the test specimen.

For detailed explanation, please refer ASTM D2303.

In Time to Track test, a constant specified test voltage is applied and the tracking time is recorded.

In erosion test, a test voltage lower than the voltage required to break the insulation is applied for an extended period of time.

The object here is to measure the erosion as a function of time of voltage application. Please contact us for a free consultation regarding test methods in ASTM D2303 and IEC EN-50397-1
