Protection relay with advanced control features

November 2014 Operator Interfaces, Switches & Relays

NewElec’s NewCode is a three-phase motor protection relay with seven inputs of differential voltages from 24 to 220 VAC or DC and four fully programmable output contacts as standard. The relay caters for the low voltage motor protection market and provides advanced protection and control features.

The ISO 9001:2000 compliant relay has a user-friendly operation, advanced LED indications for I/Os, fault indication, relay address and infrared data communications. NewcCode provides thermal overload, over and under voltage and voltage symmetry protection, as well as frequency, power factor and power dissipation measurement. More advanced features including starter logic and logic function blocks which, coupled with its communication options, make the NewCode relay an ideal solution for plant protection and automation.

The three-phase recorder allows the user to record the motor currents, voltages, thermal capacity and power factor. The motor performance can be monitored and analysed in real time. This is particularly useful when tripping occurs for no obvious reason. The recorder alleviates to some degree the need for sophisticated equipment to be carried around the plant.

NewCode has a non-volatile and volatile memory. The non-volatile memory contains a boot loader program which is used to upload the operating software program of the relay. The uploading is done from a personal computer or laptop via the USB port. This feature also enables the user to do future software upgrades without factory assistance.
