Management and Control System for Solar PV Plants

Carlo Gavazzi will be demonstrating its versatile Eos-Array modular management and control system for solar photovoltaic (PV) plants on at Nemex from 24-26 May. Also on show will be a range of accurate and reliable energy meters and analysers for renewable energy systems. A team of industry experts will be on hand to answer technical queries. The Eos-Array controller is flexible, easily scalable and is made up of a series of modular elements to provide efficient local and remote control of a solar plant, targeting small to medium- or high-power installations.

With no auxiliary bus wiring, the system is simple to install and straightforward to expand. Further cost saving is provided by the integrated string fuse protection and modularity also improves overall system reliability. String efficiency and inverters are monitored enabling operators to rapidly isolate faults, failures and inefficiencies as soon as they occur. The compact Carlo Gavazzi Eos-Array can help maximise ROI by optimising PV performance with innovative controls and monitoring. The expandable system gathers accurate and dependable data to help maintain an efficient revenue stream from a PV installation.

The controller promptly advises on activities such as blown fuses, PV module disconnection or inverter failure to enable rapid maintenance measures to be carried out, significantly reducing service time and missed production costs. There is no monthly charge for the data, which is stored on site locally, giving the user full control. The EM-series of energy meters and analysers are designed for use with PV and wind power grid-connected systems and feature a number of benefits such as a wide and bright display, compact size, easy connection and easy programming using dedicated software.

On show will be the EM10 one-phase energy meter, EM11 one-phase network analyser, EM24 1/2/3-phase energy analyser, EM26 energy analyser with 1/2/3-phase energy meter connection, EM21 three-phase energy meter with detachable display and the EM23 three-phase energy analyser. Meters are available with MID certification (Annex D).

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.
