The Problem For electrical transmission and distribution system, transformers are the most crucial assets. Failures of any sorts in transformers can lead to power outages, personal and environmental hazards and expensive rerouting or purchase of power from other suppliers. Transformer in service interruptions and failures usually result from dielectric breakdown, winding distortion caused by short-circuiting …

The Problem Submetering is the installation of metering devices with the ability to measure energy usage after the primary utility meter. Submetering offers the ability to monitor energy usage for individual tenants, departments, pieces of equipment or other loads individually to account for their actual energy usage. With submetering, a clear and accurate picture of …

Overview When a conductor is raised to a potential above that of earth, some current is bound to flow from that conductor to earth. This is true even if the conductors are well insulated from earth. The amount of current that flows depends on the voltage on the conductor, capacitive reactance from between conductor & …

Overview Nowadays, almost every industry undergoes issues related to harmonics due to the increase in usage of non-linear loads. As these loads are unavoidable because they perform important tasks like controlling or conversion, solutions to mitigate the ill effects of harmonics are to be devised. These solutions include passive filters consisting of detuned inductors and …
Overview Plant turnarounds or shutdowns, are one of the critical times in the operation of a plant. Shutdowns have an intense impact on the plant’s financial future either in positive or negative ways. Major plant shutdowns occur due to faults occurring in a system if preventive measures are not taken at the right time, whereas …
Overview The programmable logic controllers (PLC) are omnipresent in today’s manufacturing and process industries. To achieve control operations initially, mechanical relays were used. The wiring and logic involved in utilizing mechanical relays was cumbersome, replacing them by PLC offers a simple and easy solution for modifying the operation of a control system. The majority of …
