 Water –Tree Growth Tester as per ASTM D6097 is a laboratory test designed to simulate the growth of vented water trees in the solid dielectric insulating material initiated by a sharp protrusion at the insulating and conductive interface under a wet environment in a high electrical field. The system comprises, Power Source, Siemens make Logo PLC and Water Bath.

As per ASTM D 6097 – 01a, Ten compression-molded disk specimens, each containing a conical-shaped defect, are subjected to an applied voltage of 5 kV at 1 kHz and 23 ± 2°C in an aqueous conductive solution of 1.0 N NaCl for 30 days. This controlled conical defect is created by a sharp needle with an included angle of 60° and a tip radius of 3 µm.

The water-tree length and point-to-plane specimen thickness measured under microscope are used to calculate a ratio that is defined as the resistance to water-tree growth
