Introduction:
This Tester is used to verify the electrical performance of Zinc
Oxide Arrester. The instrument is suitable for various kinds of
voltage levels zinc oxide arrester de-energized testing or
energized testing, thus define the risk and inner insulation
moisture and valve aging defects.
Features
1.800 x 480 color LCD touch screen and high speed thermal printer.
2.Long distance wireless transmission. PT signal wireless
transmission distance more than 400 m, up to 2000 m;
3.Applicable for arrester de-energized test, energized test and lab
room test.
4.Three-phase current and three-phase voltage test simultaneously,
current and voltage sensor is isolated, safe and reliable.
