Partial discharge testing measures the partial discharges in the insulations that have been used on both the medium and high voltage electrical assets. Not all high voltage electrical installations are 100% safe. Others will degrade with time thus leading to the breakdown of the air insulation which triggers these discharges. The PD testing using partial discharge test equipment is used as a predictive analysis tool in order to test and monitor partial discharges in these assets and recommend the best steps to upgrade the insulation before these discharges cause major disasters.
There is a strong imperative for monitoring and testing these discharges. Left unchecked, they slowly erode the insulation over time. It is a slow but dangerous degradation that is really a time-bomb for your electrical installations. There will reach a critical point where you will be faced with an insulation failure resulting in those major electrical faults which can destroy your key electrical equipment which have probably caused millions to acquire. They may also lead to fatalities.
In order to prevent such eventualities, companies need to invest in best quality PD testing using the best partial discharge test equipment in the market. The continuous testing and monitoring using reliable and accurate data will give you a clear indication of the extent of deterioration of your electrical equipment as well as the rate of the deterioration. It will help predict the critical juncture when your electrical insulation will finally fail due to the gradual erosion of the insulation.
It is therefore a powerful tool for forestalling these kinds of disasters. There are several advantages that you will derive from the continuous PD testing and monitoring. These include the following:
Detect Problems Quickly: The defect development can be detected in the early stages by the Partial discharge test equipment. This offers you enough information about the development of the defect and you can therefore make the best plans on how to arrest this in the early stages of its development.
Offers information on the phase where the defect is located: The partial discharge equipment is always very accurate and will give you information even on the phase where the electrical discharge is happening. This is very valuable information that you would otherwise not unlock without this kind of sophisticated testing and monitoring equipment.
It will offer you even information on the type of the defect that is causing the PD discharge: There are many types of defects that you will most likely encounter such as the surface discharge forms, the corona, the deterioration of the conductive tape, void types of defects and so much more.
It is cost effective: It is a one-off cost to install the PD testing switchgear. The continuous monitoring requires very little labor cost and no effort is really required to perform these PD tests.
It reduces unnecessary maintenance: Because you have constant and accurate data by the testing switchgear on which you can base your decision making, PD testing will reduce unnecessary maintenance costs.
Requires no outage: You do not need any power outages when carrying out the tests using the partial discharge testing switchgear. It will work perfectly alongside your live power lines. With the reduction of the forced outages caused by failures in the insulation, you are also able to reduce injuries and fatalities in your medium voltage and high voltage electrical assets.
