| Description |
Electrical motors are used widely for the different applications in the petrochemical industry. Special design requirement of such motors are achieved by applying some type of protection techniques for safe operation in the explosive atmosphere. These are four type of protection techniques applicable to high tension machine as Ex ‘d’ type (flameproof), Ex ‘e’ type (increased safety), Ex ‘n’ type (non-sparking) and Ex ‘p’ type (purged and pressurized). In this paper the study is done on the different high tension (HT) motors with purged and pressurization Ex ‘p’ protection for their minimum overpressure (Pmin) location, purging time and temperature rise on stator winding and motor body. The purging time and determination of temperature rise on the stator winding of such HT Ex ‘p’ motors are described from the series of different tests conducted on different HT Ex ‘p’ motors.
