Merz Price Protection. CT 1 CT 2 secondary windings are connected in opposition so that there is no current flow in the relay operating coil V s1 V. For alternator the most severe out come of fault is the damage of stator.
Several differential schemes are applied for protection of line but Mess Price Voltage balance system and Translay Scheme are most popularly used. Therefore the cost of the designed protection system varies with the criticality. Mho and ohm relays.
In this method of protection currents at the two ends of the protected section are compared.
In this method of protection currents at the two ends of the protected section are compared. This scheme is employed for the protection of transformers against large internal short circuits. Merz-Price protection is used for. This system gives protection against phase to phase faults and phase to ground faults to the power transformers.
