DDK SAN3-40 SAN3-40M controller

• Types of digital outputs include trip-rated Form-A and SSR mechanically latching, and Form-C outputs • Form-A and SSR outputs available with optional circuit continuity monitoring and current detection to verify continuity and health of the associated circuitry • IEC 61850 Process Bus delivering advanced protection and control capabilities while providing significant savings on the total life cost of electrical substations • RTDs and DCmA inputs are available to monitor equipment parameters such as temperature and pressure

Monitoring and Metering The UR includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle.

Fault and Disturbance Recording 

The advanced disturbance and event recording features within the UR can significantly reduce the time needed for postmortem analysis of power system events and the creation of regulatory reports. Recording functions include: • Sequence of Event (SOE) - 1024 time stamped events (UR Relays) - 8192 time stamped events (URPlus) • Oscillography - Supports IEEE C37.111-1999/2013, IEC 60255-24 Ed 2.0 COMTRADE standard - 128 digital & up to 56 analog channels - Events with up to 45s length • Data Logger and Disturbance Recording - 16 channels up to 1 sample/cycle/channel • Fault Reports - Powerful summary report of pre-fault and fault values The very high sampling rate and large amounts of storage space available for data recording in the UR allows for the capture of complex events and can eliminate the need for installing costly stand-alone recording equipment.

Advanced Device Health Diagnostics 

The UR performs comprehensive device health diagnostic tests at startup and continuously during run-time to test its own major functions and critical hardware. These diagnostic tests monitor for conditions that could impact security and availability of protection, and present device status via SCADA communications and front panel display. Providing continuous monitoring and early detection of possible issues help improve system uptime. • Comprehensive device health diagnostic performed at startup • Monitors the CT/VT input circuitry to validate the integrity of all signals • Monitors internal DC voltage levels that allows for proactive maintenance and increased uptime
