Ensuring there is a substation protection design when building a substation is very necessary. Remember accidents can occur in a substation. Without good substation protection design in place you can easily loss almost everything. This can be too expensive for the company. For you to ensure the substation you are building is safe you need to incorporate high level of substation protection design in different stages of your construction. Remember in a substation the main process being carried out is the handling of electricity.
You can just imagine an accident involving electricity the way it can be dangerous in case there is no enough safety measures put in place. In your design you should make sure there are escape routes in case of an accident. Safety switches should be placed in a place where people can access them easily. This should be a consideration in your safety design of a substation. You should label clearly the purpose of the switch and the direction of turning it on and off.
