Smart Grid Battery
Xcel Energy has begun testing battery-storage technology that captures wind energy and moves it to the electricity grid when needed. S&C Electric Co. was contracted to install the battery along with the S&C Smart Grid Storage Management System (SMS). The SMS is a fast-response automatic controller that interfaces between the stored energy system and the utility, providing the ability to store energy in a battery storage system, and to control the discharge of power when required. It can address such issues as intermittent power production with production peaks and valleys, VAR control on generation, SCADA control of wind production, and improved integration of wind generation into the standard generation production schedule. The 20 50-kW battery modules will be roughly the size of two semi trailers and weigh some 80 tons. They will be able to store about 7.2 MWh of electricity, with a charge/discharge capacity of one Mw. When fully charged, the sodium-sulfur battery will potentially power 500 homes for more than seven hours. When the wind blows, the batteries are charged. When the wind calms, the batteries supplement power flow.

Rugged Mini PCs
CyberResearch MEPC-series miniature computers are ideal for thin-client applications where space is at a premium. Optional wireless LAN is available on all four models. Aluminum cases provide industrial-grade toughness while promoting good cooling without noisy fans. A 1.2 GHz VIA Esther CPU enables MEPC computers to handle firewalls and mail/print servers.
Thermal Imaging Camera
The MikroSHOT is the latest offering from LumaSense Technologies’ Mikron Infrared thermal imaging product line. This fully radiometric thermal imager allows for affordable, pocket-sized portability with capabilities normally found in larger, more expensive thermal imagers. The MikroSHOT’s Thermal-on-Visible mode allows radiometric temperature data to be displayed directly on the visible image. The MikroSHOT is lightweight (10.5 ounces) and uses off-the-shelf batteries (AC adapter included). Its 2.7-inch display and 160x120 pixel image resolution allow easy viewing of images. The MikroSHOT has a measuring range of minus 4 F to 662 F, operating temperature range of 5 F to 122 F, color alarm and autofocus at distances 1.4 yards to infinity. The SD card, USB and video output capability allow for convenient, quick analysis of the JPEG-format data on a laptop or other mobile device using common software. MikroSpec 4.0 software is included for image analysis and reporting.
Megger’s latest MIT200 insulation and continuity testers offer safety and ease of use. They have a CAT III 600V rating in line with IEC 61010-1, and they’re available in versions that offer insulation testing at 1,000 V. Despite their compact construction, MIT200 testers incorporate safety features including live circuit protection. If an MIT200 is accidentally connected to a live circuit, a warning sounds, even if the instrument’s internal fuse has failed. The instrument’s display shows the voltage present in the live circuit, and testing is inhibited. Automatic warning of fuse failure is also provided. The testers incorporate backlit LCDs with a large, analog-style arc to provide a rapid indication of results, together with a digital readout to give accurate numerical data for reports and test certificates. After a test, results are displayed until the next test is initiated, eliminating the need for a hold button. The MIT220 offers insulation testing at 250 V and 500 V. The MIT230 allows testing at 250 V, 500 V and 1000 V.
