Subject: Tips for navigating the SEL-735 Manual for new users Protection Functions : The SEL 735 relay provides

Hey everyone,

I’ve been seeing a lot of questions lately about commissioning the SEL-735 Revenue Meter. I wanted to share a quick tip for anyone diving into the manual for the first time.

If you are new to SEL devices, the sheer size of the PDF can be intimidating. However, if you jump straight to Chapter 4 (Settings) and Appendix E (SELOGIC), you’ll usually find the answers you need without wading through the introductory theory.

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.

If anyone is stuck on a specific configuration (like setting up a demand interval or configuring the IRIG-B time sync), let me know—I might have the snippet saved.

Stay safe out there.

A Note on the Manual: If you are posting this to help others find the document, it is best practice to direct them to the official Schweitzer Engineering Laboratories (SEL) website to download the PDF, rather than hosting the file yourself (to avoid copyright issues and ensure they get the latest revision).

The SEL-735 Power Quality and Revenue Meter instruction manual provides comprehensive guidance for installing, configuring, and maintaining this high-precision metering device. Designed to exceed ANSI 0.1 and IEC 0.1 S accuracy class requirements, the manual covers both the standard and portable versions of the meter.

Since you didn't specify the platform (LinkedIn, Facebook, a forum, or a blog), I have drafted three different versions of the post. You can choose the one that best fits your needs.

Critical Wiring Rules from the Manual:

1. Voltage Inputs (Terminals A, B, C, N): The SEL-735 operates at universal voltage (57 V to 240 V AC line-to-neutral). Do NOT exceed 300 V L-N or 600 V L-L.
2. Current Inputs (Terminals I1, I2, I3, IN): The device uses 5A or 1A secondary CTs. The manual explicitly warns: Never open circuit the secondary of a CT. Always short CT leads before disconnecting.
3. Power Supply: Terminals 18 & 19 (AC/DC control power). The manual specifies 125/250 V AC or 125 V DC. Using 480 V AC will destroy the unit instantly.

Chapter 6: Troubleshooting Common Errors (Section 12)

The "Troubleshooting" section is the most dog-eared part of any printed SEL 735 manual. Here is a cheat sheet of common error codes:

LCD Screen is Blank, but Power LED is On.

• Manual Fix: The display contrast may have been set to zero via serial command. Hold the Down Arrow and Enter buttons for 10 seconds to reset display parameters (See Section 3.19).

Chapter 8: Advanced Settings (Demand & Load Profile)

Many users overlook the Load Profile capabilities (Section 9). The SEL-735 has 4 MB of non-volatile memory—enough for months of 15-minute interval data.

Configuring KYZ for SCADA or Billing (Section 5.4):

The manual defines the KYZ setting:

• KYZD (KYZ Divisor): The number of pulses per kWh.
• KYZM (KYZ Mode): Select Wh (Watt-hour), VARh, or VAh.

Formula from SEL 735 Manual: Pulse Weight (Wh/pulse) = (CTR x PTR) / KYZD

Example: CTR=80, PTR=1, KYZD=1000. Pulse Weight = (80 * 1) / 1000 = 0.08 Wh/pulse. Meaning: Every time the KYZ contact changes state, you have accumulated 0.08 Wh.

Table: Terminal Quick Reference (from Manual Table 2.1)

| Terminal | Signal | Description | SEL 735 Manual Section | | :--- | :--- | :--- | :--- | | 1 | A | Phase A Voltage | 2.13 | | 4 | I1 | Phase A Current (In) | 2.14 | | 5 | I1 Return | Phase A Current (Out) | 2.14 | | 18 | L/+ | Power Supply Live | 2.9 | | 24 | KYZ-1 | KYZ Pulse Output | 2.24 |
