PD Test

What is Partial Discharge (PD) in electrical engineering?
A localized electrical discharge that only partially bridges the insulation between conductors
A complete breakdown of insulation
An intentional short circuit
A surge in voltage
Which of the following are common causes of Partial Discharge in electrical systems?
Contaminants in the insulation
High voltage stress
Low humidity levels
Regular maintenance
Short circuits
What is the main consequence of Partial Discharge in electrical equipment?
Insulation degradation leading to equipment failure
Increased efficiency
Reduced maintenance costs
Improved power quality
How can Partial Discharge be detected in electrical systems?
Using specialized PD measurement techniques such as ultrasonic or acoustic methods
Visual inspection of the equipment
Measuring the temperature of the conductors
Checking the voltage output
Which of the following materials is commonly used for insulation in electrical systems to prevent Partial Discharge?
Polyethylene
Epoxy resin
Aluminum
Rubber
Copper
