A case study discussing partial discharge damage found on a 13.8kV busbar.
Utility, Middle East – Detecting Pending Asset Failure
This case study will detail how IPEC’s PD-SGS detected a pending asset failure in a Middle East utility company.
Airport, UK – Asset Monitoring
In 2018, following a recent high voltage failure, IPEC were tasked with finding a condition monitoring solution at an airport in London.
Oil Company, UK – Partial Discharge Detected & Located on 33kV Assets
A sharp increase of Partial Discharge activity was detected on a 33kV switchgear panel by IPEC’s on-line PD Monitoring system, the ASM. High TEV PD signals were detected across the switchboard.
Chemical Company, South Korea – Fault Prevented
IPEC kept a close eye on the rise, and the criticality went from 0 to 100 in a very short period of time meaning a failure was imminent.
Utility Company, Middle East – Cable PD Detected
The examination showed extensive PD damage around the trifurcating point of the termination.
Oil Company, South Korea – IPEC ASM Detects Partial Discharge
IPEC conducted an annual data analysis report for the client, and it concluded there were high levels of Partail Discharge on cable EA4800B.
Seoul transport company, South Korea – PrecisePD Located PD on Cable
