shentongroup, Andover, urgently requires a Generator Production Engineer to join the existing team.
shentongroup are the UK’s leading Technical Experts in Standby Power, Uninterruptible Power Supplies and Combined Heat and Power Systems.
With Christmas and New Year approaching, it’s not too early to start planning which industry events to attend next year. shentongroup certainly has and we can confirm that we’ll be exhibiting at Pub16, Data Centre World 2016 and UK Ad & Biogas 2016, so read on and get the following dates in your diaries!
shentongroup successfully completed a generator refurbishment recently for a highly successful and major UK Media company.
With one day completed at Data Centre World and another already under way today, shentongroup are having a very successful time at this exhibition.
Below is a step by step guide to working through the processes.
Application Process
Step 1. Obtain the formal application document. Your local DNO may have their own preferred document, so you should contact them and ask for it.
G59 Embedded Generator Regulations
G59 is the regulation surrounding the connection of any form of generator device to run ‘in parallel’ or ‘synchronised’ with the mains electrical utility grid (National Grid). The regulation has its roots in Ofgem rules, and is administered as the Energy Networks Association Engineering Recommendation G59/2-1 “Recommendations for the connection of generating plant to the Distribution System of Licensed Distribution Network Operators – Amendment 1”.
This is relevant for all power generation, including combined heat and power units as well as generators being used for peak-lopping, or grid parallel use, greater than 16A per phase. For anything below this the Engineering recommendation G83/1-1 applies.
In years of doing projects with G59 protection shentongroup have often come across some popular myths, so we seek to dispel them here:-
“ I don’t need G59 Protection unless I intend to export power to the grid”.
Wrong. If you have any form of generator where the output is connected to the electrical systems in your building, and thus to the grid, you must protect it with a G59 relay device.
Air Circuit Breakers (ACBs) are used as circuit protection for a wide range of low voltage (up to 600V AC) applications, typically generators, MCCB distribution boards, UPS, small power stations, etc with sizes ranging from 400A to 6300A or larger. Protection is provided in either 3 or 4 pole configurations. Additional protective devices can be fitted such as undervoltage releases and shunt trip coils together with auxiliary contacts for remote signalling.
