RELIABLE INSULATION DIAGNOSTICS
bushings, current transformers and other key assets are easily obtained with the new Megger IDAX 322 insulation diagnostics analyser. This compact yet versatile instrument uses advanced dielectric frequency response (DFR) technology and operates at up to 2kV peak, allowing users to identify problems missed by other instruments and to make exact measurements even in electrically noisy environments. Despite its exceptional capabilities,

the new IDAX 322 is easy to use, with automated test flow, automatic assessment of results against international standards, and a ‘traffic- light’ display system that shows at a glance whether the asset under test is serviceable, suspect or defective. All test results are corrected to standard reference temperatures using
rustworthy test results that accurately reflect the condition of power transformers,
individual temperature correction (ITC) technology pioneered by Megger. “Traditional test
methods for insulation condition diagnostics of power assets sometimes give misleading results,” says Dr Diego Robalino at Megger. “This leads users to believe that
the asset is in good condition, when in fact, its health for normal operation might be compromised and, in some particular instances, even close to failure. These unexpected failures can be damaging in many ways, including financial, environmental and in relation to social perception. “To provide better insights into complex insulation condition, Megger has been developing, improving and supplying DFR testing technology for
more than 20 years,” he continues. “The IDAX 322 is the latest embodiment of this technology and combines unmatched high voltage capabilities with versatility, ease of use and portability. We believe that it is an important development that has the potential to protect the industry against financial, environmental and social harm by reliably detecting incipient faults.” l

BATTERY ENERGY STORAGE FACILITY ENERGISED O
ne of the biggest battery energy storage facilities in the UK has been connected to the electricity network in Burgess Hill to support renewable energy. Britain’s biggest electricity distributor, UK Power Networks, recently connected the new battery plant to the distribution network for the site’s developers,
Fotowatio Renewable Ventures (FRV), part of Abdul Latif Jameel Energy and Harmony Energy. The system of 28 Tesla Megapack lithium-ion batteries, covering about the same size as a football pitch, can store renewable energy, such as wind and solar power, when electricity demand is low and release it to the network when demand is high, supporting the renewable energy mix. The system can
flexibly store and release up to 34MW of energy, capable of serving the equivalent of thousands of homes, to smooth out the intermittency of renewable energy.

Harmony Energy and FRV will have the capability to store energy and increase flexibility of the national transmission system. UK Power Networks connected
the site to a local electricity substation via a new 1.4km underground cable that involved a 70m directional drill to overcome a special engineering challenge. The company’s switchroom was modified to accommodate the new 33,000V circuit needed to import and export electricity from the electricity storage site. Work to energise the new circuit progressed outside normal working hours to increase network resilience in the local area while engineers turned off part of the network to safely connect the site. l
