The NewFeed Relay is an ISO 9001:2015 compliant; IED (Intelligent Electronic Device).
Targeting motor and feeder protection in both the LV and MV environment multiple curve selections as well as positive, negative and zero sequence protection.
It is a micro-controller-based precision instrument with ANSI protection elements, advanced control features and switchgear controller logic integrating motor and feeder control functions with prestart, close command execution time and continuous breaker state monitoring with load current feedback to detect unauthorised operation or starting as well as breaker failure detection.
The relay is designed targeting motor and feeder protection in both the LV and MV environment multiple curve selections as well as positive, negative and zero sequence voltage and current as well as phase angles are measured as well as integrated into most relevant ANSI protection features, which can be set in disabled, warning or trip protection mode, a variety of MV and LV current transformer module blocks (CTMB) caters for different current ranges as well as easy interfacing to higher current and system voltages using interposing current transformers and voltage transformers the ratios of which are selectable on the configuration software caters for the full isolation as well as flexible range settings.
The instrumentation current transformers module block interfacing with main current and voltage transformers made for a flexible robust interface, an external core balance current transformer caters for sensitive earth leakage detection.
