Insulation Diagnostic System

In particular, the measurement of capacitance and dissipation factor allows to determine insulation condition in the high-voltage bushing or between the windings of transformers. For example, changing of capacitance value may indicate mechanical displacement of windings or insulation damage of high-voltage bushings, while increasing dissipation factor points to insulation aging, moisture ingress or to the presence of partial discharges.
Based on many years of experience in development and manufacture of measuring equipment for the named kinds of testing of high voltage equipment, we offer the instruments to complete the following tasks.
