SASPower MVSwitchgear Up to 33kV is designed and manufactured as per latest IEC standards. The SAS design team carefully selects the right components in terms of Functionality, Accuracy, Sizing of Current and Voltage Transformer, Protection Relay settings based on the System data, Operation philosophy and Interlocks.
For essential quality checks, the SAS team performs the documented scheme verification and other routine tests before the equipment is put into service. SAS Galfar uses Type Tested Power Switchgear from Original Equipment Manufacturers and performs key activities such as Design of LV Compartment, Assembly & Integration, FAT, SAT, Commissioning, Warranty and After Sales Services.
