The SEL-451 Protection, Automation, and Bay Control System has extensive logic and protection features, allowing it to be used for many applications. This application guide describes how to implement a motor bus transfer scheme in the SEL-451 for a two-source configuration.
This application guide explains how to use Microsoft Power BI and the acSELerator Database API to create interactive energy bills by using a set of prebuilt templates. This guide also explains the path of data from a variety of devices to the report and demonstrates how to build reports.
This application guide provides an example for setting the custom Modbus user map in the SEL-734 Advanced Metering System and SEL-735 Power Quality and Revenue Meter. It also includes a unique application example using a real-time automation controller (RTAC) with the FileIO Library to programmatically read a text file containing the custom user map and write the user map to the meter via Modbus.
This application guide provides typical recommendations for installing arc-flash protection using an SEL-751 or SEL-751A to improve safety and enhance protection.
When the SEL-3530 RTAC uses SEL Protocol to poll an SEL device, it must have knowledge of the ACC (and sometimes 2AC) level password of the “child” relay to perform event retrieval, fast breaker, and other command operations. If the SEL-3620 performs a password update on the SEL device, the SEL-3620 must update the RTAC internal database with the child’s new ACC and 2AC passwords or risk the RTAC losing operational visibility on the child relay. This application guide describes the steps to perform password management using the SEL-3620 with an RTAC set up for SEL Server Engineering Access as the intermediary device.
This application guide describes how to apply logic available in the SEL-735 Power Quality and Revenue Meter to detect and take action for harmonic currents exceeding those specified in IEEE 1547.
This application guide describes how to expand your Ethernet communications by using an SEL-2890 serial-to-Ethernet transceiver.
This application guide discusses features of the SEL-3622 that provide the ability to detect, prevent, and alert for unauthorized network access or physical tampering and demonstrates how to enable and configure these features in an example application.
This application guide provides an example of how to configure SEL-735 intermediate or advanced meters for the use of multiple load profile recorders with the Itron MV-90® xi meter reading software. In some cases, it is advantageous to expand beyond just one billing recorder and collect data from another selected LDP recorder within an SEL-735 Power Quality and Revenue Meter.
This application guide demonstrates how to configure the power supply of the SEL-734 Revenue Meter or the SEL-735 Power Quality and Revenue Meter to use two ac voltage sources.
