Protection and control relay

October 2013 Electrical Power & Protection

NewElec’s NewCode relay is an ISO 9001:2000 compliant, locally manufactured, three-phase motor protection and control relay designed for the LV market. It is a micro-controller based precision instrument with many user-friendly attributes and advanced protection and control features, as well as starter logic. The relay is attachable to external current transformers and software calibrated for an application. The NewCode offers Profibus, Modbus and Canbus communications protocols, making it an ideal solution for plant protection and automation.

Comprehensive motor protection is provided with time and date stamped event and fault records, as well as integrated user-configurable control logic functions and standard starter control blocks. The front-end data recorder and spectrum analyser can be used to monitor motor performance or to detect up to the 9th harmonic of any three-phase current.

The relay detects earth leakage currents with the aid of the external core balance current transformer and is configurable to operate in inverse definite minimum time (IDMT) or instantaneous definite time (IDT) mode. The relay’s simulation function can be used for personnel training or relay functionality testing.

An expansion module is available for additional I/Os, four to twenty milliamp IN and OUT, as well as RTD inputs that support four different sensor types. An optional memory module mounted on the side of the relay stores all user settings and addresses so as to facilitate relay replacements with complete ease.
