[amp_mcq option1=”required to operate the circuit breaker” option2=”absorbed by the circuit of relay” option3=”developed by the relay circuit” option4=”none of the above” correct=”option2″]<\/p>\n
The correct answer is: B. absorbed by the circuit of relay.<\/p>\n
The burden of a protective relay is the power absorbed by the relay circuit. It is a measure of the load that the relay places on the circuit. The burden is usually expressed in ohms and is determined by the relay’s coil resistance and the capacitance of the circuit.<\/p>\n
The burden of a relay is important because it can affect the operation of the relay. If the burden is too high, the relay may not operate properly. If the burden is too low, the relay may operate erratically.<\/p>\n
The burden of a relay can be reduced by using a relay with a lower coil resistance or by using a capacitor to filter the current to the relay.<\/p>\n
Here is a brief explanation of each option:<\/p>\n
