One big advantage of the PD PAC is its portability and it does not required any power supply at site to operate making it easier to move around.Also,it is versatile and does not require many sensors to test for different equipment or applications.If short term monitoring is required,the same system can be deployed for this purpose without incurring additional cost for the customers.In addition,the softwares are specially developed to detect and identify Partial Discharges based on empirical data collected from true case studies of actual problems found at sites over the years.
