What is Dissipation Factor?
Dissipation Factor is an electrical test helps defi ne the overall condition of an insulating material. A di-electric material is a material which is a poor conductor of electricity but an effi cient supporter of an electrostatic field. When an electrical insulating material is subjected to an electrostatic fi eld, opposing electric charges in di-electric material form di-poles

Multiple Technology Approach to Motor Diagnosis & Troubleshooting
The multi-technology approach to motor diagnostics means using different testing technologies to complement and validate each other. For example, when a vibration technician suspects a possible rotor problem in a critical application, and the cost to repair or replace requires a loss of production, where the motor’s cost is small compared to the incurred costs of the shutdown.

Rotor Bar Analysis Using Electrical Signature Analysis
Broken or fractured rotor bars are found as elevated Pole Pass Frequency (PPF) sidebands of line fre- quency (LF). PPF is calculated using the synchronous speed minus the running speed times the number of poles..
