5. The Hidden Gem: The "SEL-735 Quick Start"

If you don't have time to read the full 400-page manual, look for the Quick Start Guide (often included as a PDF on the shipped CD or available on the SEL website). High-accuracy revenue metering (ANSI C12

This condensed version is perfect for field technicians. It gives you the default IP address (usually 192.168.1.100 or similar), the default username/password, and the basic connection steps. Keep this printed out and taped to the inside of your metering cabinet—it will save you during a frantic commissioning session.

1. Device Overview

The Schweitzer Engineering Laboratories (SEL) SEL-735 is a revenue-accurate power quality and metering device designed for substation and industrial applications. It combines:

  • High-accuracy revenue metering (ANSI C12.20 / IEC 62053-22)
  • Power quality monitoring (EN 50160, IEEE 519)
  • Fault and disturbance recording
  • Data logging and communication

Chapter 1: Understanding the Structure of the SEL 735 Manual

Before diving into wiring, you must understand how the manual is organized. Unlike consumer electronics, the SEL manual uses a function-based index.

Error Code: V0 High

  • Meaning: 3V0 (Zero-sequence voltage) is present.
  • Fix: Check for a blown VT fuse on one phase or a ground fault on the system.

Chapter 4: Revenue Metering and KYZ Pulses

One of the SEL-735’s superpowers is revenue-accurate pulsing (KYZ outputs). Section 5 of the manual explains that the meter maintains 0.06% accuracy from 0.01A to 20A secondary.
