In this video we discuss how to set distance protection elements such that they do not trip under load conditions by using the load encroachment function found in modern microprocessor-based protective relays. We also discuss how to make sure distance protection settings comply with the NERC PRC-023 standard.

Great Video. For Solar Plants where generation is not fixed, do we enable ELOAD function? is it required for all T-line ?

[@romeroengineering]

Hi Harsh! Enabling the load encroachment function depends on whether or not there is a risk that the mho elements will trip on load. You would first need to determine what the maximum loading of the line is. This is usually given in current or apparent power, then convert that to the equivalent impedance and plot it in the RX plot with the mho circle. If the load impedance falls within the mho element circle, then enable load encroachment and set it such that it blocks the mho element from operating at the load impedance. We could always get on a call to discuss one-on-one any specific applications: www.romeroengineering.co/offers/ZEo7VkVz/checkout

can you do PRC-0025 for transmission lines

[@romeroengineering]

Thanks for the recommendation Omer! We'll consider it for a future video
