IVR Series

Three-Phase Oil Cooled
Industrial AC Voltage Stabilisers
without Independent Phase Control

IVR Series - Three Phase
Oil Cooled AC Voltage Stabilizers - 250 to 5000 kVA

IVR Series Oil Cooled Voltage Stabilisers utilize Magnetic Induction Brushless Technology to deliver highly reliable and virtually maintenance-free voltage stabilisation and protection.

The oil immersion of the stabiliser considerably enhances the system’s cooling efficiencies and as a result delivers, in terms of physical size, a highly compact solution – especially when compared to alternative air-cooled models.

Basically, they are our IVRI Voltage Stabilisers without independent phase control. When compared to the IVRI range, IVR stabilisers deliver a more cost-efficient voltage stabilisation solution for larger power environments where the need to stabilise the incoming utility mains supply on an individual phase basis is not considered essential due to the fact that there is little difference in the incoming voltages across each of the phases.

The Stabilisers can be supplied configured for either a Three Phase 4 Wire (With a Neutral) or 3 Wire (Without a Neutral) input supply.

Models are available in 15 different power ratings from 250 to 5000 kVA, being able to accommodate situations where the incoming nominal utility supply is either 380 to 415V (H/HD Series), 190 to 240V (LY/LD Series), or 440 to 480V (HX/HXD Series).

Where required, the Stabilisers can be provided as enhanced Power Conditioning solutions with the inclusion of an Isolation Transformer and/or with a standalone Main System Switchboard (MSB) – with interlocked input, output, and bypass breakers. In addition, on special request, IVR Stabilisers and their associated switchboards can be supplied as fully standalone containerized power plant solutions.
