Live HV: for the Best Partial Discharge Solutions in Australia and Beyond

Electrical machines such as generators, transformers, or industrial applications involve systems where insulation plays an important role. However, in such systems the problem of partial discharge may take place if proper installation and monitoring is not observed.

If the topic sounds unfamiliar, partial discharge is simply an electrical hitch or discharge that happens within a localized area in the insulation system. The activity usually occurs between two conducting electrodes but does not bridge the gap completely. Poor workmanship during installation, imperfect insulation system, and lack of continuous flow of current in the system are some of the causes of the condition.

Testing of partial discharge is therefore important because it diagnoses any imperfection or malfunction that may occur in the insulation system, calling for appropriate solution before the problem can be out of control. It is also important to understand that PD often occurs in systems generating 3000 volts of power or higher, but can also take place in systems with lower voltages.

Where does PD occur in the insulation system?

The activity can occur at various points within the system in places with voids, in gas bubbles (in liquid insulation), or at interface between the layers of insulation. In new electrical equipment, the problem may occur because of improper installation, poor design in cable joints, or terminations that occur on-site.

To put the activity under control, partial discharge measurement is an important activity in applications where the problem is bound to occur. Even in manufacturing plants, poor workmanship at the production stage can lead to the problem showing up in a machine in the first three years after installation.

In Australia, Live HV is a company that specializes in partial discharge solutions. Located in Melbourne, Victoria, the company provides cutting-edge online partial discharge monitoring to businesses associated with mining, milling, or smelting. Other beneficiaries of the solutions include power authorities, health institutions, trains, and any other business that utilizes medium or high voltage power network.

It is also important to note that Live HV serves clients beyond Australian borders. Companies in New Zealand and the Pacific can also benefit from quality partial discharge analysis provided by the company. Many clients may ask about what makes the company different from other service providers in the region. However, the answer is obvious, as the company focuses on delivering total reliability to avoid network failures that can lead to costly downtime or safety implications.

Some of the services provided by Live HV include:

·         Online cable PD testing

·         Cable PD mapping to diagnose fault

·         PD monitoring in switchgears

·         Offline PD testing

·         Motor, generator, and transformer PD testing

·         Thermal imaging

Left unattended, partial discharge can lead to power failures in systems, which can translate to huge expenses. It is therefore important to engage specialists to conduct regular assessment of the insulation system, identify any underlying problem, and address it accordingly using appropriate solutions. That is what Live HV stands for: to provide clients with unmatched service to ensure that their electrical systems operate smoothly at all times.
