A DETECTION DEVICE OF INSULATION RESISTANCE FOR NON-INTERRUPTION OF ELECTRIC POWER AND HOT-LINE

Title:

A DETECTION DEVICE OF INSULATION RESISTANCE FOR NON-INTERRUPTION OF ELECTRIC POWER AND HOT-LINE

Document Type and Number:

WIPO Patent Application WO/2013/081310

Kind Code:

A1

Abstract:

A device for measuring an insulation resistance in order to monitor the insulation state of electrical facilities. An insulation resistance Rins is calculated from a voltage VT that is measured by a voltage sensor in a hot line state in which a power distribution system is operating, using the discrete Fourier transformation (DFT). The insulation resistance Rins is displayed depending on individual levels so that accidents depending on the levels can be rapidly coped with.
