Answer / Chetan Singh

IEC60034-14 does not specify a specific power rating (KW) at which a vibration monitoring system for motor bearings becomes mandatory. The requirement depends on factors such as the type, size, and operating conditions of the motor. Generally, vibration monitoring is recommended for all types of bearings in critical applications, particularly those with high loads or speeds.

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
