RS ISOLSEC S.L.U

Specialists in tailor-made instrument transformers since 1954, RS ISOLSEC offer an extensive product range: manufacture and supply of instrument transformers, current transformers (CTs), voltage transformers (VTs and PTs), protection transformers, measuring transformers, potential transformers, current and voltage sensors, insulating parts in cast resin for low voltage (LV), medium voltage (MV), and high voltage (HV) applications. We develop customized solutions to meet customer specifications in markets including power generation, power transport, power distribution, industry control, and severe environments (railways, marine, mines). Our instrument transformers applications encompass energy, industrial or tariff metering, protection against overcurrent, earth fault protection, and measure of homopolar currents. Our fields of expertise include scaling high currents and voltages (up to 60,000A / 52kV) down to small currents and voltages (down to several mA / mV). Our instrument t...
