Mar 10, 2015· How much current flows through a person’s body can be estimated using ohms law (I = E/R).. The average resistance of a dry human body can be as high as 100,000 ohms, of course this varies from person to person depending on their body structure.When wet, the resistance may drop as low as 500 ohms depending on the voltage level.

Mar 18, 2018· Use Caution When Testing. Before conducting a transformer winding resistance test, it is important to observe all safety warnings and take proper precautions.Ensure that all equipment to be tested is properly grounded and treat all high-voltage power equipment as energized until proven otherwise by using the proper lockout/tagout procedures.
Jun 23, 2017· Online Transformer Tests. These diagnostic inspections are performed while the transformer in service:. 1. Dissolved Gas Analysis (DGA) A DGA is the first indior of a problem and can identify deteriorating insulation and oil, overheating, hot spots, partial discharge, and arcing. This is, by far, the most important tool for determining the health of a transformer.
