Partial discharges is the name given to an electrical phenomenon that consists of the breakdown of a high voltage electrical insulation. If they occur and go unnoticed can have very serious consequences. The key to preventing any possible problem is detecting and measuring. The measurement of partial discharges and analysis can help to avoid risks. The main reason why these partial discharges occur is the ageing of insulation.
By virtue of the high voltage levels, likely damage to the electrical insulation. Therefore, a rigorous control can save you a lot of time and money. There are several reasons why the partial discharges can begin. For example, the source of the incidence can be a cable or transformer. Determine the exact source of the phenomenon is crucial for the implementation of corrective measures immediately. One commonly used method is by detecting the coils at the end of the cable that allow the accurate detection of the problem area.
The data obtained with the help of the measurements is processed immediately in general, in situ. Partial discharges in motors and generators can help you locate the problem in time and avoid serious financial losses. Partial discharges can occur in various types of electrical equipment. For example, transformers are vulnerable to these types of events and may be permanently damaged if no partial discharges are detected in a timely manner. Other parts of electrical equipment, such as high-voltage bushings are also vulnerable to sudden ruptures, and regular monitoring of the bushing is highly recommended. The switches are another type of electrical material and which have a tendency to fail after prolonged use. The failure typically occurs on the switch due to the high currents that cross it. High voltage cables are also prone to failure, will easily deteriorate over time. In order to properly maintain all of these pieces of electrical equipment, partial discharge events must be carefully monitored at all times. Choose a team detection of partial discharges, be sure to carefully look at the specifications of the product so that it suits your requirements with precison. Specifications, such as power input, range, the memory or the maximum heart rate are very important. There are also a wide variety of special features to choose from, depending on the complexity of the task. When speaking of the high voltage equipment must have in mind the possibility of a rupture caused by partial discharges. If the problem remains unsolved deterioration occur until the computer is completely destroyed. The replacement of damaged equipment is very expensive and can be avoided by the constant and exhaustive oversight of measurement of partial discharges.
