Product Description
XI1ER1XI1ER1A / Directional Earth Overcurrent1A / Directional Earth Overcurrent for Compensated or Isolated Grids. High Precision. IEC 60255-1.FEATURES & FUNCTIONALITY1A / Directional Earth Overcurrent for Compensated or Isolated Grids. High Precision.Basic time delay accuracy: 0.5 % or ±25 ms.Basic accuracy of characteristic quantities: ±2 % of IE the setting value or ±0.002 x IN ±1 % of Ue or ±0,5 V.Real current component meas. in compensated systems: IE x cos φ.Reactive current component meas. in isolated systems: IE x sin φ. Accuracy of measured angle at Ue > 20 V: ± 6° at IE = 0.002 x IN, ± 3° at IE = 0.005 x IN, ± 2° at IE = 0.010 x IN, ± 1° at IE ≥ 0.015 x IN . 250 x In (half cycle), 100 x In for 1s, 30 x In for 10 s, 4 x In continuous

The XI1E of the PROFFESIONAL LINE is an all-purpose protection against earth faults, used for electrical machines, lines and isolated or compensated systems; it is mainly used in radial networks. Very often the XI1E can be found as backup protection at the central earthing point of the system. It detects all earth faults occuring in the system.Relay variant XI1E-R with directional current sensing is a selective earth-fault protection and is normally used in ring systems, networks with parallel feeders and in complex meshed systems.The XI1E is compliant with IEC 60255-1.Order Variants of the XI1E• XI1E1 (1 A) – ANSI 50Ns, 51Ns• XI1E5 (5 A) – ANSI 50Ns, 51Ns• XI1ER1 (1 A) – ANSI 50Ns, 51Ns, 67Ns• XI1ER5 (5 A) – ANSI 50Ns, 51Ns, 67NsWoodward is an independent designer, manufacturer, and service provider of control solutions for the aerospace and industrial markets.
