Case Studies

AF Switchgear routinely manufacture bespoke switchboard systems to be sent all across the UK. Their customers often have requirements for Power Factor Correction to be installed within the switchboard itself.

After commissioning a new HV/LV substation, a North Wales manufacturer experienced instability and tripping. We identified harmonics from VSDs as the root cause and installed Active Harmonic Filters to stabilise the system.

We developed high-performance custom capacitors for a UK defence manufacturer operating in demanding environments, delivering on both technical and environmental specs.

With limited electricity demand availability, ROM Witham couldn’t scale production. Our site services improved load efficiency and restored Power Factor control, unlocking 33% more capacity.

A manufacturing site saw rising energy costs due to failed PFC systems. Our retrofit solution with detuned filters restored performance and eliminated utility penalties.

When high harmonic voltage distortion damaged integrated PFC gear at Crown Packaging, our HPQ filters restored control, protected existing equipment, and enabled factory expansion.

Electrical Switchgear Services Ltd. needed AHF modules quickly—within their own panel. We supplied the right modules, guidance, and support to make it happen.

An energy tech firm needed specialised capacitors within 12 weeks. We sourced and modified a compatible part to meet specs and the deadline.

When legacy PFC systems began causing penalties and overload risk, we delivered and installed a new detuned PFC unit for Southern Water—ensuring grid compliance and long-term reliability.

EMCOR raised concerns about a noisy PFC fan at Siemens Worcester. We acted quickly, offered weekend support, and resolved the fault with minimal disruption.

With 10 legacy AHF units failing, Power Capacitors delivered compact replacements that didn’t need wall-mounting—restoring power quality and BMS compatibility.
