ProBeck-IPS relay
The ProBeck-IPS relay is fully configurable with the aid of frontend software or a man machine interface unit (MMI). Event records can also be downloaded with the aid of the laptop for
further analysis. All the settings are password protected. The relay has an on-board database where time and date stamped records are kept. Two types of records are kept namely fault
records (35 last faults) and event records (1400 events). In the case of event records, the user has limited access rights (read only).
The front-end also 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.
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. 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.
