PD30E PD Diagnostics System
PD30E PD Diagnostics System
Partial Discharge (PD) Diagnostics
What was once thought to be unachievable a mere 20 years ago, on site Partial Discharge (PD) diagnostics in the field has developed significantly over the past decade. Partial Discharge detection used to be consigned to special test bays in factory and laboratory environments. With the advances in electronics and software, performing PD measurements in the field has now become a routine and important maintenance check of an electrical system.
While there is a great deal of good information on PD on the internet and in technical papers, there is also a great deal of hype, misrepresentation and sales propaganda out there.
Partial Discharge is a very fast, small electrical spark or discharge that does not completely collapse the applied voltage. These discharges can, over time, degrade the insulation, resulting in a complete breakdown of the insulation, often with catastrophic consequences. PD is normally no more than a few mV in amplitude and when considering that the applied voltage is normally several kilovolts, with good modern test instruments, you are literally detecting a needle in haystack, when you detect and measure PD.
The PD series of partial discharge detectors, primarily geared at cables, allows the operator to detect and locate PD. The systems have been designed to work with the HVA Series of VLF high voltage test generators. The powerful software that comes with the PD systems has been engineered to be user friendly and flexible allowing the operator to detect and interpret PD activity coming from the device under test (DUT).
HV Diagnostics PD30E Partial Discharge Diagnostics System
The PD30E is an ultra-compact partial discharge (PD) measurement and location system that interfaces to the HVA30 HVA34 or HVA28TD VLF AC test systems. The portable combination with the HVA28TD allows the user to perform VLF withstand, Tan Delta and Partial Discharge with one easy setup. Designed for testing cables up to 25kV class cables, the PD30E uses the same user friendly powerful software suite used in all our other PD systems and allows for both the detection and location mapping of PD activity in cable or device. The PD30E comes complete in a rugged injection molded case with NIST traceable PD Calibrator
