Disconnect Switch<br />
Disconnect switches are typically designed based on porcelain insulators specifically because <strong>of</strong> mechanical<br />
stresses resulting from operation. Such stresses are even increased if grounding switches are directly attached to<br />
the disconnect switch. However, designs based on composite insulators are currently under investigation. Fig.-<br />
