SEL-T35

Time-Domain Power Monitor

The SEL-T35 is a next-generation time-domain power monitor featuring continuous waveform streaming. This device streams voltage and current waveforms at a high speed of 14.4 kHz (14,400 samples per second), capturing subtle power system disturbances and anomalies that traditional monitors might miss. When combined with the dedicated Synchrowave software, it provides unparalleled visibility for power quality analysis and system diagnostics.

Key Features

Ultra-High-Speed Continuous Waveform Streaming

Continuously records and transmits voltage and current waveforms at 14.4 ksps, allowing for the analysis of sub-millisecond voltage sags and fine noise.
Millisecond Energy Packet Analysis

Measures energy transfer at 1 ms or 10 ms intervals, enabling precise monitoring of energy flow in complex grids and systems with distributed energy resources (DER).
Advanced Harmonics and Power Quality Analysis

Supports monitoring up to the 100th harmonic, providing extensive power quality analysis and precise monitoring of system pollution levels.
Subsynchronous Oscillation (SSO) Detection

Analyzes streamed signals in real-time to identify low-frequency resonances or abnormal oscillations, issuing immediate notifications when risk thresholds are met.
Early Prediction of Incipient Failures

Detects voltage disturbances of 1 ms or shorter to identify early signs of underground cable insulation breakdown or potential transformer (PT) defects, helping to prevent catastrophic failures.
Versatile Measurement Channels

Supports four current and four voltage inputs, along with four 0–50 mA analog inputs, allowing for the integrated management of various industrial sensor data.

Power Supply Ride-Through

An integrated energy storage pack keeps the device operating and streaming for at least 7 seconds after an external power failure, ensuring no data loss during the critical moments of an outage.
Front USB-C Port

Features a modern USB-C port on the front panel for fast connection to a laptop, allowing users to update settings or retrieve diagnostic data without the need for special adapters.
Included Synchrowave Software

Comes with a license for dedicated software that enables data visualization, virtual metering, and easy tracking of power quality trends.
Backlit Pushbuttons

Designed with bright, backlit buttons to ensure convenient and error-free operation even in dark substations or control cabinets.
Flexible Connection Methods

Offers multiple connection options, including direct copper wiring or the use of transducers, to minimize installation constraints and provide electrical isolation.
Real-Time Virtual Metering

Uses the streamed waveform data to calculate and display voltage, current, power, power factor, harmonics, and flicker in real-time within the software.
