Hi all,
In a power line, as the attached sample drawing, there are two MCB with an undervoltage relay.
The MCB1 is installed in the substation and the MCB2 in the substation of the machine. The distance between them is almost 800m.
What I want to ask is if I cancel the undervoltage relay of MCB2, it will affect the protection of the transformer and load or the undervoltage of the MCB1 is enough for the whole circuit.
Thank you in advance.
