If, during operation, the protective equipment of the transformer gives an alarm or trips the transformer from the network, one should immediately investigate the reason for it. Studies may reveal whether it is a question of transf…lnkd.in/dHdnp6Zv lnkd.in/gWT9Jzy

The numerical relay settings offer the flexibility to configure the CT star point according to the specific requirements of the site. Fig. No:18 illustrates the process of selecting the CT star point using the DIGSI 5 software. In…lnkd.in/dHE2jAKJ lnkd.in/dRpEE4pR

Proper analysis of the VFD’s power and control circuit diagrams is essential for successful troubleshooting. But before starting any analysis, you must know how your system connected through VFD works and how it breathes. You must…lnkd.in/dJsZZWsQ lnkd.in/dJDaVnaA

This technical article will try to shed some light on switching devices usually installed in low voltage switchgear – circuit breakers, contactors, disconnectors, load-break switches, switch disconnectors and fuses. There are many…lnkd.in/dzdu2HGd lnkd.in/gsVhpGv

The first remedy any operator thinks of is the readjustment of the current setting via the hit and trial method. However, this method can turn hazardous in no time if the relay cannot produce a trip signal for actual earth fault, b…lnkd.in/dH8Z-_3p lnkd.in/eC9ja4V

Nowadays, if you do not consider harmonics distortion when designing a new network, you missed the whole point of the network design. Yes, really. The sooner you realize that harmonics problems are on the rise, the better. Modern p…lnkd.in/dP3sG2sk lnkd.in/ezVBe52X

Most practical power system problems are solved by using steady state analytical methods. These methods make the assumption that circuit parameters are linear, bilateral, and constant for constant frequency circuit variables. When…lnkd.in/dANidZmZ lnkd.in/g-33UK6

However, before settling on either a standard AIS, GIS, or a system that combines the two technologies, there are a number of considerations that need to be taken into account. Because there is such a wealth of data, all of which m…lnkd.in/dAqvkaX3 lnkd.in/dyq-MQQ3

Electrical systems within a nuclear power plant (NPP) deserve significant design considerations. The availability of on-site as well as off-site power plays a crucial role in nuclear power plant safety and are one of the most impor…lnkd.in/dwAmDhgB lnkd.in/gx-FMkQ

In this technical article a survey of different parts of the control and protection equipment is done. Equipment included in the control system are auxiliary power systems, protection system, metering equipment, control and regulat…lnkd.in/dSc2iyE3 lnkd.in/e2Ps6CJ

It is crucial to identify and organize the benefits and drawbacks of AIS and GIS in a hierarchical fashion in order to help with the decision-making process. After that, it is necessary to examine the aspects according to the requi…lnkd.in/dhcqaVGj lnkd.in/dyq-MQQ3
