RSISOLSEC

What we do

Specialists in tailor-made instrument transformers since 1954, RS ISOLSEC offer an extensive product range: manufacture and supply of instrument transformers, current transformers (CT’s), voltage transformers (VT’s and PT’s), protection transformers, measuring transformers, potential transformers, Rogowski coils, current and voltage sensors, insulating parts in cast resin for low voltage (LV), medium voltage (MV), and high voltage (HV) applications.

LV Current Transformers

RS ISOLSEC present their low voltage current transformers (CT) equiped with either wound primary winding, or central bushing for primary winding, bushing type, window type for busbar, cable, or both. All these instrument transformers can be fit for outdoor use.

LV Current Transformers on HV

These transformers are installed in Very High Voltage (VHV) environments using the insulation of the existing primary conductor (cable, busbar, busduct,…) for nominal voltages of 20kV – 63kV – 75kV – 225kV – 400kV – 800kV. Insulation 0,72/3kV, Ring core or split core, Assigned current up to 60 000A, Measure or Protection, Compliant with IEC, BS, VDE, ANSI, CSA and other International Standards.

LV Voltage Transformers

RS ISOLSEC offers both single phase and three-phase low voltage voltage transformers (LV VT’s) and potential transformers (LV PT’s), for the measurement of AC voltages up to 2000V.

MV Current Transformers

RS ISOLSEC produces both bushing and wound primary current transformers for medium voltage current transformer applications. Our full range comprises: wound primary, window type, French utility EDF tariff metering, and outdoor medium voltage current transformers. We also produce series reactors that can be installed in capacitor banks for cos phi regulation.

MV Voltage Transformers

RS ISOLSEC offers an extensive choice of medium voltage (MV) voltage transformer and potential transformers (PT’s) products, vacuum moulded in self-extinguishing resin. Select from single-pole, double-pole, integrated fuse, three-phase, outdoor, low induction and thermal output MV voltage transformers.
