NA016 FEEDER PROTECTION RELAY THE ECONOMICAL SOLUTION FOR THE PROTECTION OF LINES AND TRANSFORMERS — Application The 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 in ungrounded or Petersen coil and/or resistance grounded systems, the residual overcurrent protection can be used on feeders of small length in order to avoid unwanted trippings due to the capacitive current contribution of 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.

— Measuring inputs Three phase current inputs and one residual current input, with nominal currents independently selectable at 1 A or 5 A (traditional CTs) or three phase currents for low-power CT (LPCT) with selectable rated current. — Output relays Four output relays are available (two changeover contacts); each relay may be individually programmed as normal state (normally energized or de-energized) and reset mode (manual or automatic). A programmable timer is provided for each relay (minimum pulse width). The user may program the function of each relay in accordance with a matrix (tripping...
