Low cost integrated substation protection and control system
… in the digital equipment associated with the power system such as digital relays and transducers the development of integrated substation protection and control systems were possible. In this thesis the use of the currently available very sophisticated and reliable, yet inexpensive high level …

Design for ESD Reliability in High-Frequency Mixed-Signal Integrated Circuits
The design of on-chip ESD protection has become increasingly critical and difficult because of shrinking device feature sizes, high operating speed, and system-on-a-chip (SoC) environment. A complex ESD protection network can be easily exposed during normal operation and can cause the degradation …

Performance comparison of a permissive overreach transfer trip (POTT) scheme over IEC 61850 and hard-wire
… integration of systems built from multivendor power protection relays. The standard describes the rules for integration of control, measurement, and protection functions within a power system network at the substation control levels. The standard was created with the idea of eliminating wiring …

Advanced microprocessor based intelligent relay for multifunction protection system
Protective relay constantly monitors the power to assure maximum continuity of electrical service with minimum damage to life and property. Thus, they are on guard throughout - from the generation, through transmission, into distribution and utilisation. They are found in large and small systems, …

Local ecological knowledge on the population dynamics of elephants (Loxodonta africana) in the Highlands of Northwest Namibia
… on elephants in northwest Namibia so that protection measures can be planned. Given that counting and monitoring elephant populations and behaviour in such a mountainous and rocky landscape is particularly challenging, the Research Project was largely based on collating the local ecological …

Current transformers transient response modelling using electromagnetic transient program (EMTP)
… Current transformers are considered eyes for power system protection. Behaviours of protection systems depend largely on information fed to them by instrument transformers. Ferromagnetic current transformers have for many years provided practical method of current measurement, however there …
