What is BS EN IEC 60034-27-4 – Rotating electrical machines about?
BS EN IEC 60034 is a European standard on rotating electric machines that discusses insulation resistance and polarization index measurements on winding insulation of rotating machines.
BS EN IEC 60034-27-4 provides recommended test procedures for the measurement of insulation resistance and polarization index of stator and rotor winding insulation of rotating electrical machines.
BS EN IEC 60034-27-4 recommends minimum acceptable values of insulation resistance and polarization index of winding insulation valid for fully processed low and high voltage AC and DC rotating electrical machines with a rated power of 750 W or higher.
Who is BS EN IEC 60034-27-4 – Rotating electrical machines for?
BS EN IEC 60034-27-4 on rotating electrical machines applies to:
- Manufacturer of electric motors
- Manufacturer of induction motor
- Quality check personnel
- Electrical engineers
Why should you use BS EN IEC 60034-27-4 – Rotating electrical machines?
Electrical machines are usually rotating devices that create electromagnetic torque due to the magnetic coupling field. The machines that perform electromagnetic conversion of energy is called rotational converters. The rotating electrical machine consists of a stator, rotor and the air gap between them.
An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The polarization index (PI) is used as an indicator of motor insulation health and is useful in identifying the accumulation of contaminants as well as a physical change in the insulation.
BS EN IEC 60034-27-4 provides guidelines for measurement of the insulation resistance and the polarization index on stator and rotor winding insulation of rotating electrical machines. BS EN IEC 60034-27-4 also provides the Insulation resistance measurement that has been recommended and used for over 50 years to evaluate the condition of electrical insulation. It is recommended to track periodic measurements, accumulated over months and years of service or in connection with servicing and overhaul of rotating machines.
By using BS EN IEC 60034-27-4 standard you can also provide information on ageing processes, possible repair options and the recommended time interval between tests. With obedience and compliance to BS EN IEC 60034-27-4, you can efficiently manufacture high-quality products.
