- The SEL-734B delivers leading-edge control to any distribution system. The following list highlights some of the unique benefits and capabilities of the SEL-734B.
- Install the SEL-734B in applications that require conventional or LEA sensors.
+120 or 25 V voltage input ranges.
+10 V LEA or magnetic current transformer (CT) inputs.
- Monitor, trend, and log system conditions.
+Monitor active and reactive forward and reverse power flow.
+Trend power system conditions with up to 192 recording channels.
+Log years' worth of data at acquisition rates as fast as 3 seconds.
- Increase system accuracy and versatility with Instrument Transformer Compensation (ITC).
+Compensate for both phase and ratio errors over six calibration points to get the most accuracy from your instrument.
+Shift the measured signal up to ±180º. The SEL-734B can compensate for this phase shift.
- Detect high-distortion conditions with harmonic triggers up to the 50th order.
+Configure independent thresholds to target specific harmonic components.
+Map the triggers to the front-panel LEDs or configure the scrolling LCD to quickly alert local operators.
+Add harmonic binary triggers and analog quantities to the DNP3 or Modbus map to inform SCADA operators.
+Start an oscillography waveform recording when the harmonic trigger asserts for postanalysis.
+Analyze detailed harmonic data easily through the front-panel menu or the human-machine interface (HMI).
- Design
+Custom control schemes with programmable SELogic and acSELerator QuickSet design templates.
- Reliability
