Capture Every Event With the SEL-T35 Time-Domain Power Monitor
Conventional power monitors depend on phasor-based calculations to detect faults and disturbances, but energy flow changes faster than once per cycle—the typical measurement rate of these devices. Kilosample-per-second (ksps) time-domain measurements expose power system disturbances that traditional power monitors do not typically capture, allowing you to take immediate action.
The SEL-T35 precisely samples ac and dc signals and continuously streams data at 14.4 ksps and energy packets at 1 ksps to SEL Synchrowave software. This data stream includes energy packets calculated every millisecond, providing energy measurements independent of frequency and phase angles. The SEL-T35, in combination with Synchrowave software, delivers a comprehensive system for continuous waveform measurement, real-time streaming, and long-term data recording.
With the SEL-T35, you can view ac and dc voltage and current measurements in real time on the color touchscreen HMI, as though it were an oscilloscope. The low-level mA dc analog inputs measure outputs from third-party transducers, including temperature, solar irradiance, and high-energy dc voltage or current, allowing conversion efficiency calculations within SEL Synchrowave software. An integrated ride-through pack ensures that you never miss a disturbance during short-duration outages.
