It covers issues related to different failure types such as mechanical failures, overheating, chemical actions etc. and ways to…
Low Voltage Switchgear
Low Voltage Switchgear Author: Velimir Lackovic Arc Low-voltage switchgear generally refers to metal-enclosed or metal-clad low-voltage power circuit breaker switchgear that is rated for 600V alternating current (AC) and below. The metal-enclosed switchgear is completely enclosed on all sides and the top with metal sheets, has stationary primary power circuit switching or interrupting elements, or…
Generator Protection
Generator Protection Author: Velimir Lackovic Protection relays are used as part of generator protection schemes, and they are available in various configurations that allow them to be used under a variety of conditions. These protection relays protect the generator or prime mover from damage, and they also provide protection for the external power system and…
Earth Fault Protection
Earth Fault Protection Author: Velimir Lackovic Fault statistic suggests that earth faults are the most common fault type. Therefore, earth fault protection is of great importance in electrical networks. The type of earth fault protection selected depends primarily on the type of grounding method. This course describes protection principles for solidly (effectively), reactance, high resistance…
Current Transformers
Current Transformers Author: Velimir Lackovic Current transformers are a specific transformer configuration used for current measurement. The common engineering laws are applicable to the current transformers and can be used in their design. The most important roles of current transformers are: To transform currents, from a high value to a value that can be easily…
