SEL-735 Power Quality and Revenue Meter

Precise Metering for High-Value Power Systems

Five-inch, color touchscreen display model Formattable 1- and 3-line monochromatic LCD display model

Key Features and Benefits The SEL-735 Power Quality and Revenue Meter combines leading power quality capabilities with exceptional revenue metering accuracy at an economical price.

➤ Easily access data. An optional touchscreen interface displays real-time waveforms, metered data, alarms, notifications, and settings.

➤ Accurately allocate energy costs. The SEL‑735 outperforms ANSI and IEC accuracy standard requirements with a 0.06 percent Wh guarantee. It exceeds ANSI C12.20 0.1 and IEC 62053-22 0.1 S accuracy class requirements over its entire service life, eliminating costs associated with field calibration.

➤ Capture every power quality disturbance. Power quality reports with IEC 61000‑4‑30 Class A compliance and as much as 1 GB of onboard storage help visualize system conditions and store years of data. Optional continuous waveform streaming precisely samples voltage and current signals at 3 kilosamples per second (ksps) and sends the data to SEL Synchrowave® software for visualization.

➤ Share critical information securely. Simultaneously communicate with as many as ten other devices by using industry standard protocols, including DNP3, IEEE C37.118 synchrophasor measurements, Modbus, and IEC 61850. Port security settings allow three permission levels that provide controlled read and write access to the ports.

Cyber Secure Four password levels provide controlled access to metering data and ensure protection of critical meter configuration and data. Port security settings allow three permission levels that provide controlled read and write access to the ports. The meter verifies the authenticity and integrity of firmware files during upgrades by using a checksum and cryptographic signature.

Transformer/Line-Loss Compensation When the contractual billing point differs from the meter location, use transformer and line-loss compensation (TLLC) to optimize the metering location and reduce the instrument transformer costs. Both compensated and uncompensated values are stored in the meter to simplify site verification.

The VSSI recorder time-stamps voltage excursions with as much as 4 ms resolution and records indefinitely by using an adaptive sampling rate. Settings include trigger thresholds and hysteresis as a percentage of the nominal value and an automatic recording duration dependent on the length of the voltage excursion. Configure continuous waveform streaming and Synchrowave software to capture all disturbances without needing to program pickup triggers.

Distributed Generation Control

Provide automatic start and remote control to distributed generation facilities.

SELOGIC control equations support any logical or mathematical combination of measured quantities and set points to control a generator or load switch.
