Sel 735 Manual Now

Connect phase voltages A, B, and C to inputs VA, VB, and VC. Connect the system neutral to the VN terminal.

The SEL 735 is a highly advanced, multifunctional relay designed for protection, control, and monitoring of power systems. This manual provides detailed information to assist users in understanding the device's capabilities, installation, configuration, and operation.

Supports DNP3, Modbus (RTU/TCP), MV-90, IEC 61850, and Mirrored Bits communications.

Utilizes the Blondel theorem, typically requiring two Potential Transformers (PTs) and two Current Transformers (CTs).

Configure the voltage thresholds (e.g., 90% for sags, 110% for swells) to automatically trigger event reports and waveform captures. sel 735 manual

The initial chapters of the SEL-735 documentation focus on physically integrating the meter into your electrical system.

: Comprehensive guide for installation, operation, and advanced features. Quick-Start Guide

Available in standard switchboard, projection, flush-mount, and portable variants. 2. Safety and Installation Guidelines

The SEL-735 is a workhorse for revenue metering, but setting it up can be tricky if you aren't familiar with SEL's menu structure. Connect phase voltages A, B, and C to inputs VA, VB, and VC

The SEL-735 Power Quality and Revenue Meter is an industry-standard device used for advanced power quality analysis and high-accuracy revenue metering. Manufactured by Schweitzer Engineering Laboratories (SEL), this meter is deployed by utilities, industrial facilities, and critical infrastructure operators worldwide.

Specifically, keep an eye out for the "Instantaneous Quantities" section if you are trying to pull real-time data via Modbus or DNP3. The addressing can be a bit non-intuitive compared to older SEL relays, so keep that reference table handy.

Check PT fuses, physical wiring connections, and verify the PTR setting.

The SEL-735 Power Quality and Revenue Meter is a premier, high-precision instrument designed for utility, substation, and industrial applications. It sets the standard for accurate energy billing while offering advanced Power Quality (PQ) diagnostics. This manual provides detailed information to assist users

The device contains internal nonvolatile flash memory (options up to 1 GB) dedicated to historical data logging. It can store years of sequential metrics, including load profile data, voltage flicker (Pst and Plt according to IEC 61000-4-15), and symmetrical components. 5. Protocols, Automation, and Integration

The SEL-735 features Load Profile (LP) recorders that store historical energy consumption data.

Don’t try to guess the TOU logic. SEL uses a specific syntax for their control equations. Copy the examples from the manual’s appendix to ensure your billing data is compliant with your utility’s tariff rules.
