ABB Supplies Integrated Telecommunications System

ABB has been commissioned to supply a integrated telecommunications system including CCTV, security, access control and communications. The facility is being built for E.ON at Holford in Cheshire and will store gas in eight salt caverns deep underground. The processing plant consists of several gas compressors that optimise the pressure of gas stored and withdrawn from the caverns into the National Grid Transmission System.

Designed to hold over 160 million cubic metres of gas, the plant will be controlled by ABB Extended Automation System 800xA and integrated with the telecoms systems, providing a single point of access and control for operational personnel. It includes multiple workstations and two 52in wall-mounted monitors, allowing operators to visualise the entire process. It incorporates CCTV images, along with other plant process and asset-management information, increasing uptime and site security, and reducing operational costs.

The telecoms scope includes: CCTV - perimeter surveillance and plant-asset monitoring, including video recording; site security - access control and intrusion detection for site, including perimeter fence, gates, turnstiles and buildings; communications - fixed telephones and a site-wide mobile radio system; remote operation - from a remote location both production and site security visibility is provided; public address - zoned systems for alarms and broadcast messages; fibre optics - a dedicated fibre-optic network for security voice and data communications.

The System 800xA will also interface to fire and gas monitors around the plant and third-party packages such as the compressor unit controls. The combined solution will provide E.ON with an integrated process-control, safety and security system that, through the use of the System 800xA aspect-object technology, allows operators to call up process and telecoms aspects from relevant graphics.

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.
