BLACKBOX Digital Fault Recorder

Manufacturer's part number :


Manufacturer Elspec


Description :

The G4DFR is a fully featured Digital Fault Recorder with continuous recording capabilities that make it possible to analyze short transient events, long term deistrubances, as well as, trend input quantities. The G4DFR has been designed to meet with the needs of Generation, Transmission and Distribution Power System Monitoring. The G4DFR is a fully-featured Digital Fault Recorder equipped with Continuous Recording enabling it to analyze short transient events, longer term disturbances and trend input quantities such as Voltage and Current R.M.S. Values; Frequency; Active and Reactive Power; Power Factor; Current and Voltage Harmonics; Voltage Sages and Swells; Voltage Flicker; etc. The BLACKBOXDFR can be uniquely configured as either a centralized OR a decentralized architecture, to fit almost any application making it highly cost effective. The G4DFR automatically retrieves any event, including any power parameter at the highest sampling resolution and accuracy. Optimize your power system to improve reliability, shorten your fault clearance times and verify correct operation of your switchgear and other protection equipment.
