For your spinning equipment, online Partial Discharge testing is one of the best assessment tools available. While offering an expansive range of machine insulation testing services, online Partial Discharge testing is our specialty. From installing PD sensors to diagnostic monitoring to continuous remote monitoring LIVE HV can provide you with a complete service.
We are also accredited to provide the HVPD patented ‘complete network monitoring’ technique where multiple machines can be monitored from your switchboard. This is particularly useful for machines in hazardous areas.

Online PD Testing
On-Line PD testing is widely accepted as the best condition assessment tool for motors and generators rated from 6.6 kV to 30 kV. Testing can be made using portable or permanent High Frequency Current Transformers (HFCT’s) or permanently installed coupling capacitors.
Complete Network Monitoring
Complete Network Monitoring – Hazardous Areas
Using patented technology from HVPD, LIVE HV can provide complete network monitoring with HFCT sensors installed at the central switchboard. This was specifically designed for the Oil and Gas industry to enable PD measurements of HV motors installed in hazardous areas. The technique eliminates any requirement to install sensors at the machine, rather the sensors are installed in the remote switchboard.
MCSA is a non-intrusive, on-line test technique, used to assess the rotor condition of motors by analysing the frequency content of the current.
MCSA can be used in conjunction with on-line partial discharge (OLPD) testing; for the preventative maintenance and diagnosis of problems in induction motors. Through periodic testing it is possible to track and trend a machines mechanical performance, pre‑empting faults and unplanned outages.
What Can MCSA Detect?
- Broken Rotor Bars
- Dynamic Eccentricity
- Static Eccentricity
For Critical Plant it can be best practice to have permanent 24/7 monitoring which provides ultimate peace of mind regarding an assets condition. LIVE HV can provide, install & monitor a range of portable & permanent monitoring solutions with the HVPD range of technology including the patented complete network monitoring solution. We have the option of renting or purchasing monitoring equipment.
Monitoring equipment can be provided with service contracts where all the data interpretation is performed for you. Data can be accessed by the customer via cloud based web view for real-time analysis of asset condition or automatically uploaded to HVPD servers where it is instantly assessed with the HVPD Monitoring Database. Customers can be alerted to any changes in condition immediately and frequent reporting can be provided to trend an asset for accurate maintenance scheduling.
The first step in any continuous monitoring set-up is to consider the required PD sensors to provide the best possible results. There are a range of options for sensor installation which LIVE HV can advise upon.
