Power failure can occur due to equipment breakdown, maintenance, or natural events such as lightning strikes, floods, and earthquakes. A mobile transformer can overcome power failure within a minimum time frame, ensure power supply through the substation, and connect to the high—and medium-voltage lines. A mobile substation is expected to be a self-contained trailer or container equipped with the necessary high- and medium-voltage components of a complete substation, including a step-down power transformer, disconnect switches, switchgear, metering transformers, surge arresters, protection and control equipment, and AC and DC auxiliary power and control systems. Other equipment can be required to meet BWL's specific requirements. It should have maximum mobility and flexibility. Currently, BWL has 18/24/30 MVA and 30/40/50 MVA 138 kV//13.8KV Substations. BWL is looking for specifications for mobile transformers with relatively lower footprints. BWL follows the NESC, NFPA, NEC, MIOSHA, Michigan Building Codes, and other applicable codes and standards.
