OTDR Aids Fibre-Optic Infrastructure Management

The AQ1200 OTDR optical time-domain reflectometer from Yokogawa's range of multi-field testers is designed to aid the installation, commissioning and maintenance of fibre-optic infrastructure. The instrument offers a range of optical measurement capabilities in a compact, handheld package measuring 216 x 157 x 74mm and weighing 1kg.

In addition to OTDR-analysis functions, test features include a fault locator for automatically finding faulty events, plus an optional-visual fault locator using a visible light source. A further option allows optical loss testing in conjunction with a built-in stabilised light source and optical power meter with a range of +10 to -70dBm or +27 to -50dBm. The Yokogawa AQ1200 incorporates an easy-to-read 5.7in colour LCD display and offers built-in multiple-language support.

It operates at wavelengths of 1,310 and 1,550nm over distances ranging from 500m to 200km and pulse widths ranging from 3ns to 10us. Other facilities include a simple connection-test option using the Ethernet Ping test, support for an external video fibre inspection probe and multi-core fibre test capability. The Yokogawa multi-field tester series also includes the AQ1100 MFT-OLTS optical loss tester.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
