What does secondary protection look like in a distribution box
The equipment within these boxes varies: primary distribution cabinets usually contain isolating switches, circuit breakers, and residual current devices (RCDs); secondary cabinets contain large three-phase circuit breakers; tertiary cabinets contain single-phase circuit breakers. With secondary selective service, each distribution transformer must be able to supply the entire load for maximum reliability benefits. Let's make an example for clarity: A newly constructed residential area introduces a 10kV power line to a substation. From the transformer's low-voltage side (0. 4kV), power is distributed to a main distribution panel. The secondary box adopts an inner and outer door design, with a spray painted exterior. It is safe and aesthetically pleasing, and the rainproof top of the box is suitable for outdoor work.

How long is the delay protection time in the distribution box
The long-time pickup (Ir) is adjustable from 0. 0 times the circuit breaker sensor plug rating (In) (D). Long-time delay (tr) (B) sets the length of time that the circuit breaker will carry an overcurrent below the short-time or instantaneous pickup current level before. Further, the duration of the voltage dip caused by the short circuit fault will be shorter, the faster the protection operates. The fast operation of the protection also reduc-es post-fault load. The operating times of the overcurrent relays at 30-45second cycle), giving an over-all time of 90 seconds.
