Role in the system and operating principle
Operating principle
Mains, UPS, generator, rectifier and battery sources connect to suitable AC/DC buses through main protection and isolation devices. Outputs are protected according to the loads, while measurements and alarms are provided to operations.
Maintenance and lifecycle
Breakers, bus connections, insulation, thermal condition, measurement accuracy and transfer logic are checked periodically. Calculations are updated when loads or sources change.
APPLICATIONS
Engineering for the duty profile.
- Substation control and protection circuits
- UPS output and maintenance-bypass distribution
- Generator and emergency distribution
- Telecom, rail and industrial control
- Critical building and process loads

TECHNICAL QUESTIONS
Frequently asked questions
Can AC and DC distribution be addressed in one project?
Yes. Sources, loads, monitoring and maintenance can be designed within a shared project scope, provided protection devices and operating rules are verified separately.
Can an AC breaker be used in a DC circuit?
Only a device explicitly approved by its manufacturer for the DC voltage, pole arrangement and breaking capacity may be used.
Should UPS output distribution be separate?
Separate or sectionalised distribution is preferred in many projects to support critical-load selectivity, maintenance bypass and operating safety.
