D22 Digital Partial Discharge Detection System

4_a

D22 has built-in Calibration that allows calibration to be performed automatically. It injects a known PD signal from 1 pC to 1000pC into a PD test circuit to allow verification of calibration.

Software of D22 allows to generate the report by adding the company logo, customer and test object details. All measurement results, PD pattern, graphs and test object data can be saved on the hard disk or printed directly.

Partial Discharge testing is a sensitive mean of assessing the quality or condition of insulation contained within the high voltage equipment. It can be caused by poor design, manufacturing faults, mechanical damage or aging. D22 based on straight discharge detection principle, is versatile high performance digital detector designed to make highly sensitive measurements on all types of high voltage insulation systems. The ability to measure low levels of partial discharge is referred to as sensitivity. Different products have different inherent acceptable levels of partial discharge ranging from 2pC to over 1000pC.
