The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective relaying demands the utmost attention and diligence. However, when dealing with relay protection, protection engineers may inadvertently focus only on the relays. Engineers talk about selecting appropriate relays, applying correct settings, checking out …
A basic distinction can be made between system safety and product safety. Product safety has improved constantly over the past few years, if not decades. One reason for this is that various standards have been established or improved recently. Usually, norms or standards reflect the state-of-the-art in modern techniques. Using state-of-the-art measurement equipment that meets quality standards for safety minimizes …
