GIS tools for high voltages

All high-voltage generating equipment should have an indicator which signals that the high-voltage output is enabled. All high-voltage generating equipment should have provisions for external connections (interlock) which, when open, cause the high-voltage source to be switched off. These connections may be

    Explanation. All materials carrying an electric charge generate an electric field.When an energized conductor is near a material at earth potential, it can form very high field strengths, especially where the field lines are forced to curve sharply around the earthed material. The bushing controls the shape and strength of the field and reduces the electrical stresses in the insulating material.
