		<description><![CDATA[Buchholz relay is a gas- actuated relay installed in oil-immersed transformers for protection against all kind of faults. It is used to gives an alarm in case of slow developing faults or incipient faults in the transformer and to disconnect the transformer from the supply in the event of severe internal faults. It is installed [...]]]></description>

		<description><![CDATA[SELF BALANCE SYSTEM The self balance system discussed in the category &#8216; protection of generators&#8217; can also be used without any modification for transformers; but the same type of equipments should be used for both primary and secondary windings.

		<description><![CDATA[The differential protection used for transformers is based on the principle of current circulation. This type of protection is mostly used for transformers as this responds not only to inter turn fault but also provides protection against phase-to-phase faults. Following are the complicated features in transformers and there remedial measures: 1. In a power transformer, [...]]]></description>
