You're focused on optimizing power distribution efficiency. How do you ensure safety concerns are addressed?

First we have to understand that safety is never ending process. Design electrical systems should be safe? For who or for what reason ,we are protecting final product to be safe? Work 100% effective to the design document. Maybe we protect equipment to prevent potential damage.

Preventative maintenance of breakers and switches is also important so that they interrupt faults as quick as possible. The incident energy due to a fault can be greatly increase if over current protection is sluggish or fails to open as designed.

Electrical power system safety plays vital role in ensuring system is reliable and efficient. Safety issues due to design, operations and maintenance flaws not only lead to personal n process safety incidents but also seriously affect reliable & efficient supply of power to consumers. Structured Electrical safety & reliability risk mitigations help ensuring safe, reliable and efficient power systems.

As Trend of Technology continuously evolving and happening of incident cases; no limit on level of safety requirement, since scenario of risk happening, management, mitigation Plans depends; case by case. Back-up fail save redundancy for internal and external protection is key asset, procedure of safe made operation, awareness, being equipped with appropriate safety gear, Team building/work, of course at end of any incident and in any foreseeable forecast, regulation and enforcement to follow, case by case! usually, regulation and enforcement in some cases lag.

When optimizing power distribution, it is crucial to integrate safety features from the design phase to prevent failures that could compromise system integrity and operator safety. For example, the inclusion of backup systems, such as generators or alternative power supplies, can ensure continuity of power distribution and protect against unexpected failures. Furthermore, incorporating isolation mechanisms, such as disconnect switches and emergency switches, is essential to allow safe maintenance and immediate control in emergency situations, reducing the risk of accidents and damage to the system.

Having some future fear space in electrical rooms can really help when it comes time for gear replacements / upgrades. That available space allows for new equipment to be installed and energized while existing gear is running, allowing for a shorter downtime transitioning to the new.

IEEE 1584 2018 Arc Flash calculations for incident energy are more expansive and accurate than the 2002 calculations. So be knowledgable about what standard was used for the calculations.

Continues training programs of staff , encourage them to learn about new safety standards,new technologies is compulsory now a days.

Ensure that you use the right sizes of cables and protective switchgear such as MCCBs and MCBs. The load/design current should be less than or equal to the continuous current rating of the breaker, while the continuous current rating of the breaker should be less than or equal to the current carrying capacity of the cable. This is to ensure the breaker trips in case of an overload, thus protecting the cable. Ensure each selected breaker's standard interrupting capacity is higher than the calculated value of its respective prospective short circuit current. For example, it could be 6kA, 10kA, 18kA, 25kA, 36kA, or 50kA. This is to ensure the breaker is able to protect the cable without itself being damaged. Adhere to relevant standards.
