Insulators for extremely large voltages, exceeding 200 kV, might have grading rings mounted at their terminals. This improves the electrical industry distribution around the insulator and makes it additional immune to flash-about all through voltage surges.Many simplified approximations are offered for analysing and building optical systems.
