Space charge accumulation within polymeric materials has been associated with their accelerated ageing. The measurement of this phenomenon can be used to correlate space charge profiles and their evolution to ageing. In this paper, accumulated charge

The objective of this paper is to present a simple sensor based on Faraday’s Law together with an integration and amplifying stage and used this for measuring fast current pulses. Its behavior in time and frequency is tested by measuring Partial Di

Partial discharges are a clear ageing agent on insulating materials used in high voltage electrical machines. For this reason, there is increasing interest in measuring this phenomenon in an effort to forecast unexpected failures in electrical equipm

Partial discharges are not only a consequence but a symptom of insulation degradation in electrical equipment. Partial discharges are revealed outside the insulation as very narrow high-frequency pulses that were superimposed to the grid frequency hi

Modern pulsewidth-modulation (PWM) low-voltage drives are recognized as one of the most demanding applications for a motor. Pulses facing motor terminals are responsible for turn-to-turn high electrical stresses that lead to unexpected failures in st

The use of adjustable speed drives has introduced new electrical stresses in stator insulation systems. Many applications, in which the inverter and motor are placed at different locations, have led to further enhancement of these stresses and to une

The application of inverter-fed drives provides additional electrical stresses in induction motors' insulation system. This is due to steep-fronted voltage pulses responsible for high overvoltages at the motor's input terminals and to an uneven volta

In order to replace old insulation systems based on oil-paper, other materials, such as low density polyethylene (LDPE), high density polyethylene (HDPE) and specially, cross-linked polyethylene (XLPE), have been used. Characterization of new polymer

High frequency pulses can be measured by means of inductive sensors. The main advantage of these sensors consists of non-contact measurements that isolate and protect measuring equipment. The objective of this paper is to present the implementation o
