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 …
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 …
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 …
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 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 …
Capacitance and tanδ Standards are designed for traceability of electric capacitance and tanδ values at the industrial frequency 50 Hz. Standards are used for verification (calibration) of appropriate measuring instruments, …
