RELZ 100 provides three-ph se tripping orsingle-phase and three-pha e tripping and upto 24 relay output contacts c n be selected atsite to provide the required si nals for remoteannunciators and sequence f event recorders.
The weil structured design wi h free-standingfunctional units enables the a dition of distur-bance recorder, autorecloser nd breaker-failure units at low cost.
The fault locator option provides distance-to-fault calculation, service value measurementand fault recording data. The distance to thefault, which is calculated with high accuracy,using the weil known AANZA algorithm, andthe prefault and faulted current and voltagesare stored for the last three events and can beread off on the MMG-unit or transferred via se-rial communication to the AMS.
The primary service values for voltages, cur-rents, active power, reactive power and fre-quency can be read off on the MMC-unit oraftematively from the RMS.

RELZ 100 full scheme numerical distance relayis provided in a 19" equipment frame with aheight of 6U (10.5"). A mother board ismounted at the back of the equipment frame.All other units are of plug in type, and can beeasily removed. External connections are madewith standard COMBIFLEX terminal sockets.The "Test Switch" unit contains a test switchtype RTXP 18 or RTXP 24, a dc supply ON/OFF switch.

Design (cont'd) The numerical signals are then filtered in a mi-croprocessor which performs lowpass filtering.The total bandwidth of the filtered signals issuitable for protection purposes. The informa-tion is the n converted from paralIei mode to aserial communication mode and continues tothe measuring unit. The serial coded signalscan also be made available for remote commu-nication through an optical transmitter outlet onthe unit. A green LED on the front panel is litwhen the unit is in service.
In the measuring unit RLZC 100, the encodedsignals from the A/O converter unit are de-coded, and changed back from serial to paralIeimode, and numerical filtering is performed.
RELZ 100 uses a multiprocessor design withthree signal processors for the basic distancemeasuring function and up to three additionalsignal processors performing the optional func-tions.
The impedance measurement function is madein fault loop equations, using complex values ofvoltage, current and ch ange in current. The re-sulting impedance is compared against reac-tance and resistance limits determined by therelay setting. Three 16 bit single chip signalprocessors are used in the measuring electron-ics, the functions are as folIows:
Processor 1 Calculation of the three phase-earth loops for all zones.
Processor 2 Calculation of the three phase-phase loops for all zones.
Processor 3 Calculation of directional bound-aries for all six loops (threeph ase-earth and three ph ase-phase). The directional evalua-tion of each boundary is made inboth forward and reverse direc-tions.
In order to measure the same distance for allfaults, zero sequence compensation is appliedusing a KN facto r
Xo -X1KN = 3X1
The zero sequence compensation is applied tothe reactive reach only, and is selected sepa-rately for each zone.
The resistive reach is adjusted separately in theearth fault measuring loop and the phase faultmeasuring loop.In order to maintain definite directional mea-surement for faults close to the relaying point,the loop voltage signal is used in conjunctionwith a phase locked positive sequence memorysystem which lasts for approximately 100 mg.When the memory time expires, the directionalinformation which has been determined issealed in until fault current stops flowing. Thecircuit is the n reset when normal voltage is re-stored.LED's on the front of the unit indicate statusi.e.:Green LED: In ServiceYellow LED: StartRed LED: Trip
The man-machine-communication unit, RTIA,is plugged into the front of the measuring unit.This unit is used to set the relay, select the vari-
ous options, and present inform tion to the op-erator.
Before new settings can be ente ed, a storebutton must be operated. This e sures that set-tings will not be changed uninte tionally. Whenthe yellow or red LED's are lit, th s indicatesthat there is operation informatio stored. All ofthe information stored is automa ically shownon the display.
Loss of dc supply is indicated by the green LEDbeing dark.
The green LED will flash if there s a communi-cation failure between the meas ring unit andthe A/D converter unit. (The A/D onverter LEDwill be dark if the converter is not correct.) If theinternai supervision detects a fau t, the greenLED will flash.

The cho ces in set-tings and scheme configuration a e selected bycursor movement. If the self-sup ision de-tects a fault, the MMC unit can b used to local-ize the problem. Aseriai commun cation port isprovided on the back of the relay, which allowsthe MMC signals to be connected to a remoteterminal for data logging from a Ii lay monitor-ing system.For communication with RELZ 10 , two ver-sions of RMS are available. The .fference isweather the local communication etwork is anoptical star; RMS 110, or an optic Iloop, RMS160.RELZ 100 is linked to the optical etwork by anOBI-unit, RLCA 100.

For the optical RMS network plast c fibre canbe used up to a length of 30 m. Gl ss fibre canbe used for a length of maximum 00 m. Thefibre loop or star is connected to t e OBI via amodem from the SPA-ZC range.
The local telephone modem or the local PC isconnected to the opticallink by a odem, opto/RS 232. In case of a star connecti n a portex-pander is used as the gateway fro the differ-ent protections and telephone m em/PC.
