Description
Features • Protection for short-circuits and earth-faultsin unearthed, high-impedance earthed,low-impedance earthed or solidly earthednetworks • Two- or three- single phase time-overcurrent protection with start, delayed andinstantaneous functions • Low set stage with inverse time or definitetime characteristics • Instantaneous or definite time delayed highset stage • Sensitive directional earth-fault protectionfor unearthed or high-impedance earthedsystems • Independent measuring elements withindications per phase • Settable enable value of the residualvoltage • Manual or remote automatic reconnectionof the characteristic angle for measuring ofthe resistive or capacitive component of theearth-fault current • Built-in residual voltage protection forback-up • Selective earth-fault protection for smallresidual currents in solidly earthed systems • Micro-processor based relays with continuous settings for current operate values andtime delays • The protections are available with orwithout test switch and tripping relay
RXIDK 2H relay and assemblies • Single-, two-, three-phase and three-phaseto earth variants for short-circuit and earthfault protection • Independent measuring elements with; Inservice, start and trip indications per phase • Test switch, DC/DC converter and heavyduty trip relays are available as specifiedoptions • Micro-processor based time-overcurrentrelay with continuous settings for currentoperate values and time delays • Three current range variants, with wide setting ranges • Low set stage 0,015-0,65 A or 0,075-3,25 A or 0,375-16,25 A • High set stage or 0,02-8 A 0,1-40 A or0,5-200 A and ∞ *)*)16 2/3 Hz alternative version 0,075-40 Aor 0,0375-200 A and ∞ • Low set stage programmable for the following time characteristics: - Normal inverse - Very inverse - Extremely inverse - RI-inverse time - Long time inverse - Definite time delay settable 50 ms-8,1 s • Available with optional filters for differentfrequency characteristics 0,2 A Variant - 50-60 Hz sharp - 150-180 Hz sharp - 40-2000 Hz flat 1 A and 5 A Variants - 50-60 Hz sharp - 150-180 Hz sharp - 40-2000 Hz flat- 16 2/3 Hz flat • High set stage can be delayed up to 1 s forfuse selectivity coordination • Reset ratio 95% enables a setting close tomaximum load current • Recovery time < 40 ms enables small timesteps between time selective protection • Low transient overreach i.e. the relay isinsensitive to dc component in fault current.
RXIDG 21H relay and assemblies
• Pioneering method for selective sensitiveearth fault protection in solidly earthed systems
• Earth fault relay with current-dependentoperating time. The time characteristic provides complete selectivity for earth faulttripping in solidly earthed networks, whenlargest infeed is < 80% of current on faultyobject
• Wide setting range 15 mA-2,60 A
• Binary input for enabling or blocking incombination with 2nd harmonic restraint ordirectional earth fault relay
• Minimum definite time setting to achieveselectivity with instantaneous functions indistance protection at very high zerosequence fault currents
