Partial discharge is the name given to an electrical phenomenon which consists in the breakdown of an electrical insulation under high voltage levels. If partial discharge occurs and passes undetected it may have very serous consequences. The key to preventing any possible problem is early detection. Preventive measurements and analysis can help you avoid hazardous breakdowns. Purchase the best partial discharge motors and partial discharge generators at elec-di.com.



Partial discharge is a very common phenomenon nowadays and the main reason why it occurs is the aging insulation. Under high voltage levels, the electrical insulation is very likely to suffer a breakdown. When this breakdown occurs, the consequences can be catastrophic. The electric equipment is usually destroyed after such an occurrence and the financial losses are immense. Therefore, thorough monitoring can save you a lot of time and money along the way. Measurement and detection equipment such as partial discharge motors and partial discharge generators can help you prevent unwanted situations.

There are various sources from which a partial discharge phenomenon can commence. For instance, the source of the occurrence can be a connected cable or transformer. Determining the exact source of the phenomenon is crucial because it allows corrective measures to be taken immediately. One commonly utilized method is using detection coils at the cable's ends which allow the accurate detection of the trouble area. The data obtained with the help of measurements is usually processed immediately, on location. The most reliable interpretation of the gathered data is the one made by a specialist, as partial discharge signals can be very confusing to an inexperienced interpreter. For instance, if partial discharge occurs in a resin insulated splice it can be very dangerous as opposed to a discharge which takes place in an oil insulated splice. Partial discharge motors and partial discharge generators can help you locate the problem in time and avoid serious financial losses.

Partial discharge may occur in various types of electrical equipment. For example, transformers are vulnerable to these types of occurrences and may be permanently damaged if the partial discharge is not detected in a timely fashion. Other pieces of electrical equipment, such as on-load taps, are very likely to fail because of component fatigue, misalignment, contact wear or overloading. High voltage bushings are also vulnerable to sudden breakdowns and regular bushing monitoring is highly recommended. Switchgear is another type of electrical equipment which has a tendency to fail after prolonged use. The failure usually occurs at the breaker level because of the high currents that cross through. High voltage cables are also prone to failure because they easily become deteriorated over time. In order to keep all of these pieces of electrical equipment functioning properly you should thoroughly monitor partial discharge occurrences at all times. When choosing a piece of partial discharge detecting equipment, make sure you carefully look at the product specifications so that it fits with your precise requirements. Specifications such as power input, range, memory or maximum pulse are very important. There is also a wide variety of special features to choose from, depending on the complexity of the task.

When discussing high voltage equipment you must take into consideration the possibility of a breakdown caused by partial discharge. The phenomenon is very common in aged high voltage equipment and flawed insulation. If the problem is left unresolved it will propagate until the equipment is entirely destroyed. Replacing damaged equipment is very costly and can be avoided by constant and thorough partial discharge monitoring.
