The Basics of Partial Discharge Testing | HV Get Price!
What is Partial Discharge? When speaking of partial discharge, the most important standard that every expert will refer to is IEC 60270: High-voltage test techniques – Partial discharge measurements.This standard applies to the measurement of PD in electrical apparatus or systems when testing with AC voltage up to 400 Hz or with DC voltage.

Partial Discharge is a degenerative phenomenon that affects the electrical insulation of medium & high-voltage equipment. Partial discharge (PD) is the best early warning indicator of electrical insulation degredation in assets operating at 3.3 kV and above.Monitoring · Products and Services · Sensors · Training · Our Values · About Us
PARTIAL DISCHARGE TESTING (PD TESTING)Get Price!
6/4/2019· Studies show that over 85% of disruptive failures in high voltage (HV) and medium voltage (MV) equipment are Partial Discharge related. Partial Discharge action ultimately leads to failure. Our PD testing service does not require shutdown and is the best way to plan maintenance, repair or replacement activities in a cost effective and efficient.

· PDF 文件What is Partial Discharge (PD) •PD only occurs where there is a gas (air, SF6, hydrogen) between the two conductors •The conductors must have a high voltage between them, creating an electric stress •If the electric stress in the gas exceeds 3 kV/mm of spacing (for most dry gases at 100 kPa), then electrons are stripped from the gas atoms
Partial Discharge Testing: What It Is and What It MeansGet Price!
· PDF 文件sient voltage and continuous voltage ratings. In practice, testing to determine the inception voltage, and de-rating from the inception voltage by a factor related to transients determines the continuous rated voltage. PARTIAL DISCHARGE TESTING IN PRODUCTION Once the continuous rating is established, a convenient 100% production test is needed.
