Fuse Cutout Indicator

Telescada announced its FireFly FCI-Fuse Cutout Indicator. The FireFly makes finding a dropped fuse cutout quick and easy. When the fuse blows and the cutout drops to the inverted position the FireFly activates a flashing high intensity Red LED.

The fuse can be seen up to a mile away at night so line crews can keep their eyes safely on the road while searching for the fuse. No more hunting with a spotlight. The FireFly electronics are encapsulated in UV stable moisture resistant epoxy. The FireFly’s internal lithium ion battery will last up to 20 years in both hot and cold environments. The FireFly’s clip design permits installation of the FireFlyà¢â€ž- on an installed fuse with a shotgun hotstick.



Underground Cable Fault Tester

HD Electric Co., a Textron Inc. (NYSE:TXT) company, now offers its new Underground Cable Fault Tester, the UCT-8, a lightweight one-piece tool that is used to test underground de-energized primary shielded voltage cables for faults. The tool will digitally analyze the data gathered during a test to declare a cable ‘good’ or ‘bad’ with zero interpretation required on the part of the end-user.

Test results for underground DC leakage are clearly displayed as an analog bar graph along with an indication of a good or faulted cable. A self-contained 8kV high voltage source powers the tester using a 9V lithium battery, making the UCT-8 a compact single hotstick operation tool for testing cable. There is also an integrated safety circuitry that detects cables which have not been properly de-energized, alerts the user of the problem, and shuts down the test to prevent system damage. An automatic shutoff feature helps the battery to last longer.

Substation Communications and Analysis

Schweitzer Engineering Laboratories (SEL) has added Time-Domain Link (TiDL) technology, a substation solution that digitizes analog signals, to its SEL-400 series relay product line. The TiDL solution replaces copper cables with fiber-optic cables. It is cybersecure and simple to apply, with no network engineering and no external time reference required.

Because of the nonroutable protocol, the direct fiber connection between field modules and the relay in the control house, there’s no need for switches or routers. In a TiDL implementation, SEL-2240 Axion devices are located close to the primary equipment in the substation yard and act as field modules. TiDL’s simple point-to-point architecture transports the data over fiber-optic cable to a TiDL-enabled SEL-400 series relay in the control house. The Axion’s 24 kHz sampling rate improves the accuracy of metering and frequency tracking, and its modular architecture allows the user to select analog input, digital input and digital output modules to match the application. Relay settings remain the same as those in current SEL-400 series models, providing consistency and simplicity.

Mobile Emergency Platform

SecuraTrac announces its next generation mPERS mobile emergency pendant, the MobileDefender Model S (MD-S). The model S (MD-S) is developed on the same platform as the powerful MobileDefender and introduces new capabilities that will help to ensure the safety of those who use the MD-S and the SecuraTrac platform.

Companies that dispatch employees into unknown environments and situations can rely on the MD-S to relay information about employee locations while providing them with an instant connection to help if an emergency occurs. In addition to state-of-the-art location technologies, the MD-S also offers a built-in Fall Advisory capability. The MD-S can detect horizontal and vertical movement so if an employee falls on the job or is knocked over, he or she does not have to initiate a call for help.
