Dissipation/Power Factor and Capacitance (Tan Delta) Measurement on Rotating Machines
The insulation is the most sensitive part of rotating machines. The lifetime of a stator winding depends on how effectively the electrical insulation can prevent any occurrence of winding faults.
Weak spots can already occur in the insulation during manufacture or impregnation with cast resin, through the stresses of daily operation (for example in the form of soiling) or general aging.
With capacitance and dissipation factor measurements, also known as tan-delta measurements, changes in the insulation can be diagnosed. Aging processes, changes in the structure of the insulation or moisture ingress can, for example, increase the dissipation factor. The increase in the dissipation factor during the "tip-up” test reflects the condition of the insulation.
CPC 100 + CP TD15 + CP CR600
The CP TD12 and CP TD15 are accessories for the CPC 100 and CPC 80 for performing power/dissipation factor and capacitance measurements on rotating electrical machines. The CP TD12 and CP TD15 include a high-voltage source, reference capacitor and measurement electronics. It can generate output voltages up to 12 kV respectively 15 kV, currents up to 300 mA and achieves laboratory precision, even in environments with strong interferences.
