Content Overview:  De-Energized Data Analysis

• Utilizing resistance, inductance, and impedance for fault localization to determine the condition of the windings.
• Identify insulation anomalies utilizing data from timed resistance tests, surge/impulse testing, and high potential tests.
• Examples for testing provide visual indications of the symptoms which normally accompany problems in motor performance.
• Helpful illustrations provide a means of determining the rotor and stator relationship by essentially providing a profile representing the effect of rotor impedance on stator inductance utilizing the rotor influence check.
