Pre-Training Assessment for the Training Program: Substation Automation Sys & Application

The Name *

In power system protection the sensitivity means that the system *

works every time during faulty condition
must only isolate the faulted equipment and leave as much of the healthy system connected
detect faults and not open a healthy system e.g. operate on the minimum current possible
main operating under normal transient overload conditions e.g. transformer inrush current

Circuit breakers are essentially *

current carrying contacts called electrodes
arc extinguishers
transformers to isolate two systems
circuits to break the system

One of the following is not a part of power system protection components *

Current and voltage transformers
Overcurrent, circuit breakers and fuses
Batteries, communication channels
Overload relays

The function of the current transformer is to *

convert the current from AC to DC
step up the line current
step down the line voltage
step down the line current
