Insulation Diagnostic System
Testing of high-voltage equipment
In particular, the measurement of capacitance and dissipation/power factor allows to determine insulation condition in the high-voltage bushing or between the windings of transformers. For example, changing of capacitance value …
Current transformers (CT) calibration
Being the important part of electricity metering circuits, the current transformers are liable to calibration during their manufacture, after repair and within operation. For calibration during manufacture, as well as …
Voltage transformers (VT) calibration
The key elements of electricity metering circuits are voltage transformers (VT). They should be calibrated during their manufacture, after repair and within operation. We offer VT calibration sets, using two …
Burdens calibration
Verification of the CT and VT burdens is a challenge, since impedance-admittance of the named burdens with the required precision should be measured in conditions, equal to the conditions of …
Precision measurements of Capacitance & Tan Delta
Precision measurements of the capacitance and dissipation factor are necessary for metrological support of verification and calibration for standards of capacitance and dissipation factor, and for scientific research and metrological …
