Medium Voltage Soft Starter For Driving Critical Ventilation Fans

Product: HRVS-DN
Motor ratings: 6600V, 1MW
Category: Medium Voltage Soft Starters

With nearly 1000 employees, this gold mine is considered to be Tanzania’s largest underground mining investment. Solcon’s HRVS-DN medium voltage soft starters were specified for controlling the fresh air ventilation fans in this massive underground mining venture. Starting these four 1MW fans with a 6.6KV, 300A soft-starter not only eliminates the high inrush current that disrupts the power grid on every direct-on-line start, but it also allows for constant monitoring of the fan’s “vital signs” for preventative maintenance purposes. This is accomplished via the advanced motor protection system in the HRVS-DN soft starter.
