		<description><![CDATA[Merz price circulating current system protects against phase-to- ground and phase-to-phase faults. It does not protect against turn-to-turn fault on the same phase winding of the stator. It is because the current that this type of fault produces flows in a local circuit between the turns involved and does not create a difference between the [...]]]></description>

		<description><![CDATA[The biased circulating relays are useful because they allow non-similarity between two sets of C.T.s. the restraining coil is inserted in series with one of the phases, while the operating coil is connected to the central tapping and the neutral pilot wire as in fig 4. Only one biased relay is shown for simplicity. The [...]]]></description>

		<description><![CDATA[This type of protection provides a continuous check on faults within the points, where the C.T.s are used as in shown in fig 2. There are two sets of C.T.s; each set is mounted on either end of the stator phase. The secondaries of these current transformer sets are connected in star and their ends [...]]]></description>

If this generator works in parallel with other generator sets it will start working as a synchronous motor running at synchronous [...]]]></description>
