“…This is consistent with many other studies [8]- [9]. Ageing temperature also influence the EL emission with LDPE aged at lower temperature (310 K) has higher EL intensity than that of higher temperature (350 K) [7]. However, very limited studies were conducted on the effects of frequency of applied voltage on the behavior of EL emission.…”

“…However, the characteristics of the EL emission can be affected by several factors such as applied voltage, applied frequency, ageing material and types of material used in a particular study. The characteristics of EL phenomenon in virgin and thermally aged low density polyethylene (LDPE) at varying applied voltage has been discussed elsewhere [7]. It was found that EL intensity increases with increasing applied voltage for both virgin and thermally aged LDPE.…”

A good insulator for high voltage cable has low dielectric loss, reasonable flexibility and thermo-mechanically stable. However, prolonged application of electrical stresses on the cable will degraded the cable; physically and morphologically. Electrical degradation in high voltage cable can be detected using electroluminescence (EL) method. Electroluminescence is a phenomenon that occurs when the atoms of a material are being excited due to the application of and external high electrical stresses. There are several external factors that affect the behaviour of electroluminescence emission such as, applied voltage, applied frequency, ageing of material and types of materials. . In this paper, the EL measurement is employed to determine the effect of applied frequency on virgin LDPE at fixed and varying applied voltage. It can be observed that EL emission increases as applied frequency increases with increasing voltage applied. However, interesting EL behaviour is observed when varying frequency is applied from 10 Hz to 100 Hz.
