Relay protection sensitivity formula km

The relay settings are in terms of impedance that is R and X Total Positive sequence impedance of protected line with reference to primary ZPL = [ZPL (Ohms /km)*Protected Line Length (km)] ZPL W. T Primary *(CT ratio/PT ratio) Reactance of. This technical report refers to the electrical protections of all 132kV switchgear. All calculations are based on the available documentation/ information. These settings may be revaluated during the commissioning, according to actual and/or measured values. Protection selectivity is partly. Line ZLL and second Adjacent Long Line Z2LL can be calculated. INTRODUCTION This paper provides a reference for inexperienced and experienced engineers alike to identify characteristics of the transmission line and system that should be considered in calculating settings for transmission lines. © 2025 Industrial Calculator.
