The Usefulness of Partial Discharge Analysis

By: Clint Jhonson

If you are among the numerous people responsible for ensuring power for different communities, plants, refineries, hospitals and other institutions, you definetely need to rely on an accurate diagnostic equipment which alerts you regarding any possible failures before it is too late. Luckily for you, nowadays you have at your disposal a wide range of reliable equipment to choose from.

Partial discharge represents the dissipation of energy provoked by a buildup of localized intensity of the electric field. This phenomenon is manifested in electric and acoustic pulses, being detected with the help of a host of exterior measurement techniques.

Nowadays, partial discharge measurements are meant to interpret the partial discharge phenomena and to assess the quality of the electrical equipment. It is known that limitations and errors in measurements have been debated for a long time and that many have tried to demonstrate the drawbacks of such measurements. However, partial discharge measurements are of vital importance for those of you who want to make sure that there are no problems with their electrical equipment.

Furthermore, partial discharge measurements are very popular for the monitoring of the condition of the installation and they have become essential in the quality assessment of the insulation. Due to these measurements and to the partial discharge analysis, people have at their disposal vital information regarding several aspects of insulation ageing, information that proves to be more than useful in the case of verification of the equipment integrity and diagnosis.

By means of partial discharge analysis, you can easily avoid unexpected in-service failures, you can find the problem and correct it before the failure of the electrical system, you can assess the quality of maintenance repairs, improve the overall reliability of your system and you can accomplish all this while your system is still functioning.

Nowadays there are many companies that offer a wide range of solutions for partial discharge, ranging from various discharge meters to digital detectors. The partial discharge analysis can be performed on screened environments, factories and other locations while partial discharge measurements are recommended for detecting insulation defects of cables. The measurement techniques are favored by the electricity industry, being efficient and widely applicable.

The partial discharge measurements represent a universally accepted technique which gives indication regarding the state of the insulation while partial discharge analysis is a noninvasive technique which monitors the integrity of the insulation. The discharge analysis is an efficient device which allows customers to avoid failures and to reduce their maintenance costs. This analysis is used to identify deterioration mechanisms such as slot discharge, internal voids, wedge and winding looseness. These problems need to be monitored and corrected because they can lead to catastrophic failures of the system.

If you are aware of how many accidents happen because of electric failure and poor insulation and if you want to have a partial discharge analysis, than we recommend resorting to a professional company which provides quality services. On the internet you will find many companies which offer their services in this field of expertise, but we advise you not to choose the one with the cheapest services. Electric insulation is a serious issue and therefore it should be treated as such.
