SEL announces the release of an advanced digital transducer optimized for smart distribution monitoring and automation. The SEL-734T Advanced Digital Transducer, available for just $1,144, includes a full set of monitoring, recording, and reporting capabilities. An optional enclosure provides weather-tight protection and space to mount network radios, power supplies, and encrypting transceivers. A standard 14-pin connector at the bottom of the enclosure delivers a true plug-and-play system for smart grid projects.

The SEL-734B Advanced Monitoring and Control System from SEL delivers cutting-edge capacitor bank control to distribution capacitor banks. Priced at just $1,344, the SEL-734B enables precise control to improve power quality and system efficiency. Unique features include three-phase monitoring and control, harmonic measurements, custom programmable logic, and Ethernet communications.

The SEL-734 Advanced Metering System is the latest addition to our list of products available with conformal coating. Simply choose the conformal coat option on the SEL-734 model option table to add an extra layer of protection to your meter.

 A simple surface-mount version of the SEL-734 Advanced Metering System is now available at a reduced price over standard monitoring and control devices. Replace monitors and transducers; monitor real-time power, energy, and power quality; and communicate this data in real-time with the new surface-mount SEL-734. Priced at just $1,194, the surface-mount monitor provides a low-cost monitoring and control solution for distribution and integrated power systems.

Significant updates in acSELerator QuickSet® SEL 5030 Software help speed commissioning, data retrieval, and analysis tasks when paired with the SEL 734 Advanced Metering System.

SEL is excited to announce the newest version of the SEL-734P Advanced Metering System. This portable power quality (PQ) meter is secured in a ruggedized case. Inside, you’ll find three-phase voltage and current inputs, voltage leads, and split-core CTs—all standard.

Once again, SEL has increased the capabilities of the SEL-734P Advanced Metering System With Advanced Power Quality Monitoring. Waveform capture with 8 kHz resolution is now available in up to 10-second durations. To facilitate retrieval of these large reports, the SEL-734P now compresses the waveform files prior to transmission. In addition, serial ports now communicate up to 115.2 Kbps. Combined, these upgrades reduce waveform event retrievals by a factor of ten.

SEL has made significant enhancements to the SEL 734 Advanced Metering System that expand applications for power quality metering, distribution monitoring and automation, revenue metering, industrial metering, and portable applications.

In response to increased demand, SEL is offering a 40 percent price cut on prewired outdoor enclosures for the SEL-734 Advanced Metering System.

SEL recently sponsored an electrical engineering senior design project at Washington State University in Pullman to develop a solar-rechargeable electric vehicle with grid-tie integration.

Starting November 7, SEL-734 and SEL-734P Advanced Metering Systems will ship with 32 and 128 MB of memory,respectively, significantly increasing availability of voltage sag/swell/interruption (VSSI) reports, waveform captures, and  days of load profile memory.

With five years of continuous meter development, the SEL-734 Advanced Metering System meets virtually any metering need, with price and quality unmatched by any other vendor. Versatile mounting options transform the SEL-734 into a rack, appearance, retrofit, draw-out, A-base, socket, flush, projection, wall, indoor, and outdoor meter.  Below are ten simple mounting options that you can purchase today to help replace ageing legacy meters and simplify new installations.

In December, SEL employees noticed the lights blink twice. Office workers lost unsaved files when their computers rebooted. Manufacturing employees saw their pick-and-place, autoinsertion, or test stations rebooted. In total, a short 100 ms voltage sag cost SEL $30,000 in lost productivity.

There is a popular misperception that draw-out meters save time and money. Below are a few myths and facts about draw-out meters as well as a cost-analysis tool that will help you demonstrate why the SEL-734 Advanced Metering System is a superior solution.

Due to the perceived difficulty of installing new meters, some substation, power plant, and industrial integrators may be postponing plans to upgrade their aging draw-out and switchboard-mounted meters.  With a wide variety of retrofit bezels, there’s no need to cut sheet metal to retrofit a new meter. Within minutes, you can enjoy the quality provided by a new SEL-734 Advanced Metering System.

Do you mount your high-end socket meters in an outdoor enclosure?  SEL now offers a replacement for expensive, high-end socket meters housed in heavy steel enclosures with the SEL-734/734P Advanced Metering System, mounted in a durable, lightweight enclosure.
