IEC 60034-11 Rotating Electrical Machines, Part 11: Standard Test for Thermal Protection

EUROLAB laboratory provides testing and compliance service within the scope of IEC 60034-11 standard. This part of IEC 60034 specifies requirements for the use of thermal protectors and thermal detectors incorporated into the stator windings or located in other suitable locations in induction machines to protect them against serious damage from thermal overloads.

IEC 60034-11 Rotating Electrical Machines, Part 11: Standard Test for Thermal Protection

It is valid for machines manufactured in accordance with IEC 60034-12 with voltage limits specified in IEC 60034-12. Protection of bearings and other mechanical parts is not included.

Thermal protection systems are based on the protection or monitoring of sensitive machine parts against extreme temperatures. This requires the selection of the appropriate thermal protection device suitable for both the type of protection required and the machine component to be protected.

This standard does not detail the methods of protection available or specify the method of protection to be used for specific applications, but rather the temperature of the protected parts that must not be exceeded in the event of a malfunction or abuse of the machine.

The requirements are not to guarantee a "normal" machine life for all conditions of use, but rather to prevent both failure and accelerated premature thermal aging of the winding insulation.

The requirements are a compromise, as the level of protection should not be set low enough to cause uncomfortable tripping nor high enough to allow continuous operation at temperatures that will seriously affect the life of the winding insulation.
