The PD-SG1 is a Switchgear PD detection and location instrument. The unit detects TEV signals generated by internal discharge as well as acoustic discharge generated by surface tracing or corona. The dual CC-TEV sensors allow for accurate location of PD in Switchgear to 8cm.
The PD-SGS is a dual transducer PD detector for Switchgear. The instrument detects TEV signals generated by internal discharge as well as acoustic discharge generated by surface tracking or corona.
Partial Discharge is attributed to the failure of 80% of electrical plant. Early detection of PD can be essential in protecting equipment and personnel. By incorporating expert Partial Discharge assessment and investigation by IPECs professional team of service engineers and consultants a full assessment of key plant offers advantages to the asset managers.
Our range of Partial Discharge monitors are designed for application on critical assets; including MV, HV and EHV cables, Switchgear and accessories. Partial discharge data collected from distributed monitors is stored on a central database. Customers have password protected access to this data directly over the Internet allowing them to browse the data and analyse plant condition from any PC.
IPEC supplies Partial Discharge products and conducts PD testing around the world, either directly or via our comprehensive network of agents. Including: Australia, Austria, Belgium, Brunei, Canada, China, Egypt, France, Germany, Hong Kong, India, Indonesia, Malaysia, Philippines, Saudi Arabia, Singapore, South Korea, Spain, Taiwan, Thailand, United Arab Emirates (UAE) and USA.

Partial Discharge (PD)

IPEC are experts in On-line Partial Discharge (PD) testing of MV and HV plant. We develop world leading technology for the detection and location of PD in cables, switchgear and accessories. The ASM, our PD monitor for permanent installation is used on over 3,500 HV assets around the world; by both utilities and industrial clients.

Based in Manchester in the UK, IPEC offer turnkey solutions for asset monitoring and testing. Our products range from simple to use instruments for routine spot testing to sophisticated permanently installed systems that can, for instance, be used to monitor every joint and termination on a 20km long EHV cable.
