Director DII DFR DDR

Director DII DFR DDR

Using the Microsoft Windows 10® operating system, DII features complete Transient and Long-Term Phasor Data Recording, Analysis, and Transmission. E-MAX DII has a maximum capacity of 128 Analog and 256 Digital directly connected channels.

The networking capabilities of DII combined with Windows 10® provides the power and capacity to monitor and collect data from other substation equipment. The TCP/IP addressing and data handling also allow communications with a Master Station and other devices. The DII system includes complete remote control of both the DII and any connected E-MAX DFRs.

Sensors

Software triggers (sensors) are standard for E-MAX Director DII DFRs. Each DFR locally stores the trigger information. All trigger information is user-settable — locally or remotely.

Analog Sensors: Over-, Under- limit and rate software sensors on each channel
Symmetrical component, harmonic, frequency, swing and power sensors.
Operation Limiters Individual Channel: Software Settable up to 15 minutes per fault

Event Sensors: Trigger on ALARM (operate) and/or RTN (return-to-normal) for each channel.

Processing of Record Data

The DII Recording System continuously monitors all channels. If triggered, the DII will record data to memory and process according to user settings. This System automatically identifies fault type and calculates distance to fault. All E-MAX DFR systems can print, display, transmit and e-mail recorded and calculated data automatically or upon operator request. Conversion of record data to COMTRADE and PQDIF formats may be done automatically or upon operator request.
