false indications, low sensitivity, and difficulty of fault interpretation have recently been …

This paper aims to update the review of diagnostic techniques for rotating electrical
machines of different type and size. Each of the main sections of the paper is focused on a …

Real-time winding insulation condition monitoring is becoming an important research topic
in response to increase in high availability and reliability demands in modern drives. In this …

Inverter-fed machines are widely used in industrial applications. In inverter-fed machines,
the insulation ageing is accelerated due to the high dv/dt and transient overvoltage …

Online condition monitoring of winding insulation has been proved to be an effective means
to improve the reliability of an inverter-fed machine, but little work has been done on the …

A failure of insulation is one of the main reasons for electric machine outage. Online
condition monitoring (CM) of an incipient degradation of turn insulation could eliminate the …

Online stator winding insulation monitoring is becoming an important topic in recent years
and many online monitoring methods have been proposed. In these methods, the online …

With the wide application of inverter-fed motors (IFMs), it is necessary to monitor the
groundwall (GW) insulation status to guarantee the reliable operation of motor drive system …

The insulation system's dielectric of the electric motor is very often subjected to severe
electrical stress generated by the high dv/dt seen at the machine's terminals. The electrical …

The use of the common mode current for stator winding insulation condition assessment has
been extensively studied. Two main approaches have been followed. The first models the …
