Load growth is one of the main drivers that challenge electric distribution planners to determine the most reasonable method to accommodate the new loads.

To accommodate load growth, previous design criteria required adding another transformer to substation.

The use of SMART Distribution Automation Control System (DACS) is an alternative to installing new substation transformers.
SMART DACS controls internal substation circuit switching and distribution circuit switching to prevent substation transformer overloading under a single transformer outage.
Remote Control (RC) distribution switches will automatically transfer load to one or more adjacent substations.

Our SMART DACS system is designed to send out notification via pagers or e-mails when single contingency transformer loading gets to 85% and again at 90%.
When single contingency transformer loading gets to 95% then the SMART DACS system is automatically armed and notification is sent via pagers and e-mail.

DACS Fault Detection and Sectionalizing to avoid circuit lockout.
• A fault on distribution circuit occurs.
• Circuit breaker trips open and closes back.
• Fault still present, thus circuit breaker opens again.
• Circuit breaker stays open for 25 seconds.
• DACS algorithms analyze RC switch data to determine location of fault.
• RC switches are opened and closed to isolate fault.
• Circuit breaker closes and holds – No circuit lockout.• Avoids third substation transformer through fault.
