SEL-735 Now Offers Continuous Waveform Streaming
As we continue to develop the SEL-T35 Time-Domain Power Monitor, customers with existing SEL-735 Power Quality and Revenue Meter fleets are asking for similar features. To support this growing industry request, SEL enhanced the SEL-735 to stream 3 kilosamples per second (ksps) sampled voltage and current signals into SEL-5703 Synchrowave Monitoring and SEL-5702 Synchrowave Operations software. The Synchrowave software will record, display, and trend these data plus provide access to the stored data (see the example diagram).
Future enhancements in 2025 will include a virtual meter function with subsynchronous oscillation calculations and detection, a virtual phasor measurement unit, disturbance detection, and magnitude trending. In addition, the integration capabilities will expand to include an MQTT protocol interface to IT systems. This will allow real-time streaming into any third-party local or remote server—including cloud computing. The most frequent ask for this capability is from data center operators with large variable loads that can cause voltage disturbances and oscillations on the interconnected utilities’ distribution and transmission systems.
We have an opportunity to teach this real-time streaming and analytic capability to electric power utilities and to end users with large variable loads and rapid large power pulses.
The SEL-735 3 ksps streaming is now available, with Synchrowave Monitoring/Operations support by November 1. You can start talking to existing or prospective SEL-735 customers about this streaming and recording capability utilizing our existing resources:

SEL will offer the SEL-735 3 ksps stream as a $1,000 protocol and software package ordering option with a reduced-price adder for meters that include the IEC 61850 protocol option or a software license package.For questions, for help with quotations, or to request an SEL-735 firmware upgrade, please contact Alex Kenney, lead product manager.
