Reference Answer
### (a) Important Parameters and Reasons for Recording
Two critical parameters for the condition monitoring of electrical machinery are **Temperature** and **Vibration**. These are leading indicators of developing faults and form the cornerstone of a predictive maintenance strategy.
**1. Temperature**
Temperature is a primary indicator of the operational health and efficiency of electrical machinery. All electrical machines generate heat due to inherent losses, but an abnormal rise in temperature signifies a potential failure mode.
