Protection RelaysNA016FEEDER PROTECTION RELAYTHE ECONOMICAL SOLUTION FOR THE PROTECTION OF LINESAND TRANSFORMERS— ApplicationThe relay type NA016 can be used in radial networks as feeder or power transformer protection.In solidly grounded systems the residual overcurrent protection can be used on feeders of any length, while inungrounded or Petersen coil and/or resistance grounded systems, the residual overcurrent protection can beused on feeders of small length in order to avoid unwanted trippings due to the capacitive current contributionof the feeder on external ground fault.The NA016 protection relay may be shipped with traditional CTs or low power (LPCT) current inputs.The relay complies with CEI 0-16 requirements.52TCSTA di faseControl functions5051- Protective & control functions50/5150N/51N74TCS50METERING- I L1.I L3,I EAlternative - Oscillography- Events & Faults log- Data Logger51Low powerCTs (LPCT)50N51NCOMMUNICATION- RS232- Modbus RS485NA016 - Flyer - 09 - 2011Phase overcurrentResidual overcurrentTrip Circuit Supervision
— Measuring inputs— Self diagnosticsThree phase current inputs and one residual current input, withnominal currents independently selectable at 1 A or 5 A (traditional CTs) or three phase currents for low-power CT (LPCT) withselectable rated current.— Output relaysFour output relays are available (two changeover contacts);each relay may be individually programmed as normal state(normally energized or de-energized) and reset mode (manualor automatic).A programmable timer is provided for each relay (minimum pulsewidth). The user may program the function of each relay in accordance with a matrix (tripping matrix) structure.— Binary inputsThree binary inputs are available with predefined functions: IN1 acquisition of 52b auxiliary contact for CB position capture IN2 acquisition of 52a auxiliary contact for CB position capture IN3 Trip circuit Supervision (TCS).All hardware and software functions are repeatedly checkedand any anomalies reported via display messages, communication interfaces, LEDs and output relays.Anomalies may refer to: Hw faults (auxiliary power supply, output relay coil interruptions, .). Sw faults (boot and run time tests for data base, EEPROMmemory checksum failure, data BUS,.).— Firmware updatingThe use of flash memory units allows on-site firmware updating.— Programming and settingsAll relay programming and adjustment operations may be performed through MMI (Keyboard and display) or using a PersonalComputer with the aid of the ThySetter software.The same PC setup software is required to set, monitor and configure all Pro N devices.ThySetter— ConstructionThe NA016 protection relay case is suitable for flush or rackmounting.— MMI (Man Machine Interface)The user interface comprises a membrane keyboard [1], a backlight LCD alphanumeric display and eight LEDs. The green ON LED indicates auxiliary power supply and selfdiagnostics, The yellow LED START, no-latched, indicates Start of the I ,I , I , IE , IE elements The red LED TRIP, no-latched, indicates Trip of the I , I , I ,IE , IE elements The red LED 1, latched, indicates Trip of the I , I , I elements The red LED 2, latched, indicates Trip of the IE , IE elements The red LED 3, no-latched, indicates the 52a state (CB position)[2] The red LED 4, no-latched, indicates the 52a state (CB position))[2] The red LED 5, no-latched, indicates the TCS state[2].Note 1- Keys(CB open ) and(CB close) are disabledNote 2 - Enabled only with Logger option— Data storage[3]Several useful data are stored into a non volatile memory. Sequence of Event RecorderThe event recorder runs continuously capturing in circularmode the last one hundred events upon trigger of binary input/output. Sequence of Fault RecorderThe fault recorder runs continuously capturing in circularmode the last twenty faults upon trigger of binary input/outputand/or element pickup (start-trip). Settings recordingFollowing some setting changes the last ten changes are recorded in circular mode (Data Logger CEI 0-16) Trip countersNote 3 - The data-logger is available according to the CEI 0-16 standard; version with Logger must be requested when ordering.— Communication— MeteringNA016 provides metering values for phase and residual currents,making them available for reading on a display or to communication interfaces.Input signals are sampled 64 times per period and the RMS valueof the fundamental component is measured using the DFT (Discrete Fourier Transform) algorithm and digital filtering.The measured signals can be displayed with reference to nominal values or directly expressed in amperes.Two communication interfaces are implemented: One RS232 local communication front-end interface for communication with ThySetter setup software One RS485 port using ModBus RTU or IEC 60870-5-103 forcommunication with remote monitoring and control systems.— Digital Fault Recorder (Oscillography) [4]Upon trigger of tripping/starting of each function or external signals, the relay records in COMTRADE format: Oscillography with instantaneous values for transient analysis. RMS values for long time periods analysis. Logic states (binary inputs and output relays).Note 4 - A licence for the digital fault recorder function is required.2NA016 - Flyer - 09 - 2011
