Motor Dielectric Insulation & Surge Protection
Motor Dielectric Insulation & Surge Protection
(OP)
Please advise how to select/specify adequate dielectric insulation on medium voltage motors.
a- Could be any economic advantage to specifify lower insulation level adding surge protection (capacitor & arrester)for similar level of reliability?.
b- There is any experience of motor dielectric failure caused by switching surge with vacuum devices?.

RE: Motor Dielectric Insulation & Surge Protection
Please advise how to select/specify adequate dielectric insulation on medium voltage motors.
a- Could be any economic advantage to specifify lower insulation level adding surge protection (capacitor & arrester)for similar level of reliability?
///Yes. In terms of protecting the motor insulation from the voltage surges, spikes, etc. that are most detrimental to any insulation, in general.\\\
b- There is any experience of motor dielectric failure caused by switching surge with vacuum devices?
///Yes. There might be some closely related content in IEEE and IEE publications:
