Faults on prime mover (Prime moveris the component that is used todrive the generator and may be combustion engines (the case of diesel generator sets), gas turbines, steam turbines, wind turbines and hydraulic turbines) and associated systems will not be discussed, since they are usually defined at mechanical design stage of the equipment. Protection against stator windings phase-to-phase faults is performed through a differential relay, which principle was previously discussed at other sections. All E-series relays, including our E-series motor relays, use the same software interface for easy access to information and programming of settings. Overexcitation can be explained by the following equation: Where B is the magnetic flux density or magnetic induction or core flux (unit: tesla T), V is the applied voltage (unit: volt V) and f the frequency (unit: hetz Hz). Also they are used for protection of the external power system or the processes it supplies. from different types of faults which OCCUrs in power system. Directional Type Relays These relays work on the direction of current or power flow in the circuit. Protection Relays Overview. Operation in this mode will not produce overheating unless rated power and approximately 105% rated voltage are exceeded. Contact this tutor. There are mainly two type of possibility to protect a Genset, the first one Protective relays to detect fault that occurs outside the DG Set & the another one is Protective relays to detect fault that occurs inside the DG Set. Compare this product Remove from comparison tool. Over Current pickup = 4.9 x 25% = 1.225 A. Large Size Generators (>40MVA) Multilin G60 The G60, a member of the UR family of protection relays, provides ultimate protection for AC generators. When such a type of fault occurs phase voltage decreases and a zero-sequence voltage appears; this voltage is detected by a voltage relay (ANSI/IEEE/IEC code 60) connected to VT. Stator ground or earth faults protection depends of stator grounding. The protection against rotor earth-faults may be provided by a relay that controls the insulation of the rotor by applying an auxiliary AC voltage to the rotor or a voltage relay in series association with a high resistance (linear and non-linear resistors combination is the common method used nowadays) connected across the rotor circuit, the center point of which is connected to ground through the coil of a sensitive relay (ANSI/IEEE/IEC code 64). Transformer-Electrical Protection Types: Over Current/Earth Fault-50/51Protection Under Impedance/Distance relay Protection-21 Differential Current Protection-87 Restricted Earth fault Protection-64H Three Phase Overload Protection-49 Over Fluxing Protection-24 Over Voltage-59/Under Voltage-27 Protection 2. . GE Numerical Relays for the generator protection are essential as the Generator is one of the most significant elements of the power system and is the main source of generating power in the whole system. The machine and its auxiliaries are supervised by monitoring devices to keep the incidences of abnormal working conditions down to a minimum.

ANSI index . There are protection functions against phase faults, ground faults, loss of excitation (LOM), over- excitation, overvoltage, unbalanced currents, abnormal frequencies, motoring, dead machine energization, breaker failures and system faults. Generator faults are usually classified into internal and external faults; internal faults are due to problems within the generator components and external faults are due to abnormal operating conditions and faults on external networks. 10/01/2021), (DOCX 19 KB,
