FAQ'S
A PSS/CSS is a factory-built, weather-proof substation that integrates MV switchgear (RMU/VCB), a distribution transformer, and an LV switchboard in one enclosure for fast deployment, smaller footprint, and safer operation.
Typical configurations support 11/22/33 kV primary at 50 Hz with secondary 415 V, and transformer ratings up to about 2.5 MVA; final voltage class, fault duty, and capacity are sized to project requirements.
Segregated MV/Tx/LV compartments, internal-arc-considered design options, IP-rated doors, mechanical/key interlocks, and clear mimic labeling reduce risk, speed isolation, and cut outage time during maintenance or faults.
Systems can include numerical relays, multifunction energy metering, fault passage indication, event logging with time-stamping, and remote monitoring/control via standard industrial protocols for SCADA/PLC.
Ideal for space-constrained urban networks, commercial campuses, metro/rail stations, industrial estates, brownfield capacity upgrades, and renewable evacuation where quick commissioning and compact footprint matter.
