Loss Factor / Capacitance Test
The PDTech DELTAMAXX system measures current through a reference capacitor and test object. The current is measured by the voltage drop across shunt resistors. A 16-bit A/D converter processes these voltages. The phase angle difference between the high voltage and this current is determined by a novel algorithm, which allows the calculation of the loss angle and automatic elimination of several potential error sources.
Partial Discharge Measurement
The DELTAMAXX is configured to extract Partial Discharge pulses from the coupling capacitor internally. Partial Discharge measurement does not require external shunts or additional components, that is, coupling impedance, pre-amplifier, signal processing, and digitising all takes place in the measuring unit.
