Downstream of the HVB/HVA transformer, compensation impedances equip MV networks with neutral point connection (aerial-underground rural networks). Developed as part of the Enedis MALTEN project and installed in source stations, compensation impedances allow: • The creation of an artificial neutral point separate from the HVB/HVA transformer. • Compensation of the network's total capacitive current through automatic tuning. • The operating of zero-sequence protection, by ensuring a sufficient active current in the single-phase fault. • The creation of an artificial neutral point separate from the HVB/HVA transformer. • Compensation of the network's total capacitive current through automatic tuning. • The operating of zero-sequence protection, by ensuring a sufficient active current in the single-phase fault. • Phased compensation impedance, adjusted using vacuum switches activated by a command control switch connected to the network's permanent auscultation system. • Hermetic materials, in a mineral oil bath, for an exterior installation. • ONAN cooling mode. • Lifting by the 4 rings located on the top cover.
