SEL manufactures high-quality cables for connecting a variety of devices. You can order cables to specific lengths to meet your needs. Each cable is quality tested to ensure reliability and proper operation.
This webinar describes scalable fault location, isolation, and service restoration (FLISR) solutions that use SEL recloser controls, communications devices, automation controllers, and software to locate and isolate permanent faults and restore power …
It's possible to get more out of a basic feeder protection relay without adding complexity. We've combined protection, monitoring, and control in a simple, compact package in the new SEL-851 Feeder Protection Relay.
This webinar introduces the SEL Blueframe and Data Management and Automation applications. During the webinar, you will learn how these new solutions support your efforts in increasing system security, efficiency (ease of use), and data utilization.
This webinar focuses on the SEL-735 Power Quality and Revenue Meter with a color touchscreen display. During the webinar, you will learn how the display simplifies meter setup, data access, troubleshooting, and testing. We will provide examples of how…
This webinar demonstrates how you can create and customize your own reports using energy and power quality metering data from SEL meters. During the webinar, you will learn how to retrieve and store SEL-735 Power Quality and Revenue Meter data with
In the past, power systems were dominated by linear loads and power generation sources. Today, this simple situation no longer exists and power systems include an increasing number of nonlinear loads and sources.
This webinar discusses how an SEL powerMAX remedial action scheme (RAS) solution helps the bulk power system function closer to stability limits and prevents blackouts. We also cover how to operate transmission corridors m…

This application note describes the SEL Network Global Variable List (NGVL) communications protocol and how it can be used within a decentralized control application to share data between processes.
El documento anexo permitirá configurar variables analógicos como eventos en el Registrador Secuencial de Eventos (SER) y posicionarlos en la base de datos del controlador de automatización en tiempo real (RTAC).
The purpose of this application note is to describe how an SEL-3355 Rack-Mount Rugged Computer can be monitored via Simple Network Management Protocol. Instructions on how to configure the SEL-3355 for monitoring via SNMP are given within.
Application Note -The use of traditional relay-to-relay communications is limited due to the nontime-correlated nature of the information sent between the relays. Using the real-time control capability in certain SEL relays to time-align data between two relays adds an entire new family of applications to protective relays.
Application Note - Using the SEL-735 to Display Multiple Metering Values
Application Note - This application note describes an SEL solution for creating a SCADA server or gateway to interface substation equipment and apparatus with a SCADA master station.
Application Note - Physical surveillance is a critical part of any physical security program. With the increased awareness of cyberterrorism, the focus for securing a control network has shifted from physical security solutions to electronic security solutions. Both physical and electronic security perimeters are critical to the overall protection of the control network. The North American Electric Reliability Corporation (NERC) physical security standard (CIP-006-1) outlines the minimum set of required controls to physically protect critical cyberassets. The required controls include physical access controls, monitoring, logging, and log retention.
Application Note - This application note discusses the features of the SEL-2411 Programmable Automation Controller (PAC) and SEL-2440 Discrete Programmable Automation Controller (DPAC) and the benefits of using this hardware for ingredient dispensing, blending, and mixing applications.
Application Guide - Many renewable energy resources, such as solar and wind, utilize dc to ac converters for electrical grid interconnections. During the dc to ac conversion, an inverter produces harmonics due to switching and nonideal power factor. Typically, a utility installs a capacitor bank on a distribution system for voltage and VAR support, but these capacitors also provide harmonic isolation and power factor correction that are perfect for interconnecting renewable energy resources.
