Abstract

In recent years, the improvement in optical technology has increased the use of Optical Instrument Transformers (OIT). The active parts of many OITs are placed in SF ₆ or N ₂ filled insulating structures. The challenge with using these insulating gases initiated the replacement of them with polyurethane foam, which is frequently used in low-voltage switchgears. The insulation of an OIT was modeled by foam filled tubes: 61.0 cm (24″) long, 20.3 cm (8″) diameter and electrode gap 15.2 cm (6″), and electrode radius 1.27 cm (0.5″). The AC and lightning impulse breakdown voltages of these samples were determined by a large number of tests. The repeated lightning impulse test was conducted by using 600 impulses with a peak voltage of 120 kV. The partial discharge measurements were also investigated.
