PROTECTION RELAY WITH ADVANCED CONTROL FEATURES
Product News Thursday, June 13, 2013: NewElec (Pty) Ltd
The design of this product accentuates the need for user friendly operation in that it has advanced LED indications for I/Os, fault indication, relay address, infrared data communications and the ever ready settings memory detachable module for easy relay replacement and paramatization.
The micro-controller based precision instrument offers advanced protection and control features with starter logic functions. The relay is designed to cater for the low voltage motor protection market and is available in different current models. The current transformers, including the core balance current transformers are external.
The relay is fully configurable with the aid of front-end software or a man machine interface unit (MMI). Event records can also be downloaded with the aid of the MMI onto a memory stick for further analysis. All the settings are password protected. The relay has an onboard database where time and date stamped records are kept. Two types of records are kept, namely fault records (40 last faults) and event records (1660 events). In the case of event records, the user has limited access rights (read only). The front-end has a data recorder and a spectrum analyser which could be used to analyse motor performance and supplied power quality respectively. The spectrum analyser can detect harmonics up to the 9th harmonic on any of the three phase currents.
NewCode 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.
A unique feature is added to the relay in the form of simulation. This function could be used for personnel training or relay functionality testing.
