The NewFeed Feeder Safety Relay is designed to focus on Microgrid feeder safety between photo voltaic farms and the standard energy grid in each the LV and MV distribution environments.
The NewFeed Relay measures voltage, present, optimistic, damaging and 0 sequence, part angles, energy issue, harmonics, THD and unbiased earth leakage ranges, permitting the implementation of full ANSI safety options for Microgrid feeder safety as properly motor safety with a number of curve picks (IEC60255-8, NINV, VINV, EINV, MINV, DT, IT, I2T, I4T) and directional present parts to cater for parallel feeder functions. All housed in a 45mm din rail mounted enclosure with clear descriptive fault , area enter and relay output LED indications, with inner totally configurable logic and statistic recordings.
A variety of MV and LV present transformer module blocks (CTMB) caters for various present ranges with straightforward interfacing to larger present and system voltages utilizing interposing present transformers and voltage transformers, the ratios of that are selectable on the configuration software program, catering for the total isolation in addition to versatile vary settings. A separate CBCT caters for earth leakage detection.
The NewFeed relay is configurable with assistance from configuration front-end software program. The relay has an on-board database with time and date stamped 36 fault data and 940 occasion data. The configuration software program has a full-fledged complete information recorder and spectrum analyser bundle, which can be utilized to analyse motor efficiency or feeder energy high quality respectively.
Superior management options and switchgear controller logic, integrating motor and feeder management capabilities with prestart, shut command execution time and steady breaker state monitoring with load present suggestions to detect unauthorised operation or beginning in addition to breaker failure detection.
The relay is an IED (Clever Digital Machine) with selectable communication protocols Modbus/TCP, PROFINET and IEC61850.
The relay is South African designed and regionally manufacture ISO 9001:2015 compliant.
