Analyser Used in Hydrogen-Vehicle Refuelling Trial

A Process Hydrogen Analyser from Quantitech is performing critical safety analysis in what is said to be the UK's largest ever cross-sector hydrogen-vehicle refuelling trial. The trials are being managed by Sheffield-based energy-storage and clean-fuel company ITM Power, which has deployed an H2scan Hyoptima 720 analyser as it undertakes trials of the company's Transportable Hydrogen Refuelling Station (Hfuel); a self-contained module suitable for refuelling hydrogen-powered road vehicles and forklift trucks.

Hfuel generates hydrogen by electrolysis, compresses it, stores it and dispenses the gas on demand at high pressure. The refueller is currently being used across the UK for the company's Hydrogen On Site Trials (HOST), which have already experienced broad support from organisations such as UK local authorities, DHL, UPS, the RAC, Tarmac, Amey, May Gurney, Scottish Water and Stansted Airport.

The 720 is a solid-state sensor configured to operate in background gas streams having up to 95 per cent relative humidity and temperatures up to 100C. A vacuum pump is used to draw the source gas into the monitor and a vacuum regulator and flow meter are used to control the process stream to the sensor. It is capable of measuring gases from two alternate sources and of undertaking field calibration without removal from the system.

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.
