Example a) Setting of Relay R1 Since the relay is on secondary side of transformer, our calculations will be referred to secondary side. s.e.p – training centre chapter 1 interfacing pc with relay . Latched Outputs: This function simulates lock out relay (LOR) operation. Overload relay is the one of important device for motor control.It can prevent our motor from overheat or winding burning due overload of ampere. IDMTL characteristic for time multiplier setting (TMS) = 1 according to British Standard given in the following figure1: Figure1 Solution : At relay point C, the relay … 2.1 Differential Relay Settings Calculations MiCOM P63X Relay Type: MICOM P63X Required Data Ratings of the Power and Current Transformers MVA Voltage Ratio Rated Voltage in kV (HV Side) Rated Voltage in kV (LV Side) Vector Group CT Ratio (HV Side) CT HV Side Vector Group CT Ratio (LV Side) CT LV Side Vector Group … (see Figure 1).The relay characteristic is shown in Figure 2.The C.T. Protective relay functions and data. The manual can be used as a technical reference during the engineering phase, installation and commissioning phase, and during normal service. Guidelines For Relay Setting November 2019 114. settings. Suitable relay settings and the selection of current transformers are illustrated with examples. Relay Setting Calculation rev.1.pdf - Free download as PDF File (.pdf), Text File (.txt) or read online for free. RLD= total loop resistance from relay to CT. Use AS 3008.1.1 to calculate RLDif exact value not known. Our digital library saves in compound countries, allowing you to acquire the most less latency times to download any of our books gone this one. PDF | The practical way of calculating differential protection settings for a Relay (e.g. The currents seen by the relay are affected by the CT ratio and connection hence the values of the secondary currents before compensation. 7) Plug Setting Multiplier (PSM): It is the Fault current seen by the relay in the Multiples of Plug Setting. Other methodologies and techniques may be applied to calculate relay settings based on specific applications. This paper. A short summary of this paper. File Type PDF Relay Setting Calculation Guide Relay Setting Calculation Guide When people should go to the book stores, search launch by shop, shelf by shelf, it is really problematic.
