The is the essential technical reference for installing, programming, and maintaining the highly accurate SEL-735 Meter manufactured by Schweitzer Engineering Laboratories (SEL) . Designed for sub-station, power plant, and industrial environments, the meter outperforms standard utility-grade devices. It meets strict ANSI C12.20-2015 Class 0.1 and IEC 62053-22 0.1 S standards.
For medium or high-voltage systems, instrument-grade Potential Transformers must step the voltage down to standard secondary levels (typically 115V or 120V line-to-line). Connect the secondary side of the PTs to the meter's voltage terminals, maintaining strict phase orientation. Current Connections (Current Transformers - CTs)
The sel 735 manual is a powerful tool that is essential for any engineer or technician working with this versatile metering device. This guide has provided a roadmap to its structure, from physical installation and basic setup to advanced power quality monitoring and custom logic control.
If you can tell me the (e.g., substation, submetering) or the version of the SEL-735 (e.g., horizontal/vertical, touchscreen) you are working with, I can give you more targeted information from the manual. sel 735 manual

The first stop for most engineers is the metering configuration. The SEL-735 manual does an excellent job of breaking down .
Enter the primary-to-secondary ratio of your PTs. For example, a 14400:120V PT has a ratio of 120 . If no PTs are used, set this value to 1 .
Beyond basic billing data, the SEL-735 captures complex power quality events. These features allow engineers to diagnose grid instability and root out equipment malfunctions. Waveform Capture and Event Triggering The is the essential technical reference for installing,
In the manual, you will find that are provided, such as Level 1 ("OTTER") and Level 2 ("TAIL") for initial configuration. The manual also details the process of setting up a network connection by adjusting your computer's IP address to match the meter's default gateway to establish communication. Beyond basic setup, the software allows you to customize meter identifiers, scaling factors (CTR/PTR), and display points .
Requires three PTs and three CTs to accurately measure phase-to-neutral voltages and individual phase currents. Terminal Connections
