The effect of load flow is to cause a shift in this voltage relative to the relay current because the relay current (Ir) and the total fault cur rent (If) are out of phase with each other . The shift in phase in the voltage is more pronounced as the impedance, Zt, gets larger relative to the impedance, Zs.
Can i set traps on my propertyDiesel brothers new season 2020of this relay are such that its operating time is approximately doubled for a reduction in current from 7 to 4 times the relay current setting. This permits the use of the same time multiplier setting for several relays in series. 5. Calculations : Calculation of relay operating time: In order to calculate the actual relay operating Electrical Protection System . Design and Operation 1. Function of Electrical Protection Systems. The three primary aims of overcurrent electrical protection are: Personnel injury protection Equipment damage protection Coordination and proper discrimination of operation . In this section we will consider only the latter two aspects. The effect of load flow is to cause a shift in this voltage relative to the relay current because the relay current (Ir) and the total fault cur rent (If) are out of phase with each other . The shift in phase in the voltage is more pronounced as the impedance, Zt, gets larger relative to the impedance, Zs. evaluate the zone 3 relay settings on all transmission lines operating at 230 kV and above for the purpose of verifying that each zone 3 relay is not set to trip on load under extreme emergency conditions.6 In each case that a zone 3 relay is set so as to trip on load under protective relays for the protection of power transformers, with an emphasis on the most prevalent protection schemes and transformers. Principles are emphasized. Setting procedures are only discussed in a general nature in the material to follow. Refer to specific instruction manuals for your relay. The references provide a
