When Control and Protection is Critical

With the stability and reliability of MV and HV infrastructure vital to the economy, secondary protection systems detect abnormal conditions and then isolate those parts of the electrical network to:

• Prevent system instability;
• Prevent equipment damage to plant exposed to the fault;
• Minimise the extent of damage at the fault site and collateral damage to adjacent facilities
• Minimise the safety risk; and
• Minimise the extent of any power outage.
