What is the primary purpose of insulation resistance measurement in electrical systems?

• To measure the voltage drop across electrical components

• To assess the efficiency of conductors in carrying current

• To determine the effectiveness of dielectric (insulation) in resisting electrical current flow

• To calculate the total power consumption in a circuit

What principle is the insulation resistance measurement based on, and what does a high resistance value indicate?

• Ohm's Law (R=V/I), and a high resistance value indicates poor insulation


• Kirchhoff's Law (V=IR), and a high resistance value indicates good insulation


• Faraday's Law (E=mc^2), and a low resistance value indicates good insulation

• Coulomb's Law (F=k q1 q2 / r^2), and a low resistance value indicates poor insulation

What does a higher Polarization Index (PI) value indicate in the context of insulation resistance testing?

• Better insulation polarization and recovery

• Poor insulation characteristics

• Increased leakage current

• Reduced dielectric strength

Which of the following conditions is NOT detected by Sweep Frequency Response Analysis (SFRA)?

• Broken Clamping Structures.

• Open Winding and Shorted Turns.

• Partial Winding Collapses.

• Core Movement and Displacements.

Sweep Frequency Response Analysis (SFRA) is also called as:

• Frequency Sweep Diagnostics

• Spectral Sweep Evaluation

• Impedance Spectrum Analysis

• Fingerprint Test

Degree of Polymerization (DP) refers to the extent of ______________ in the insulation material.

• Polymer Grafting.

• Polymer Chain Degradation.

• Polymer Chain Transfer.

• Polymer Crystallization.
