Save ‘Size’ and ‘Cost’, with a right selection of ‘VA burden of your Current Transformer’

Cost Effectiveness-The need of an hour In the present COVID-19 situation, where already our productivity is affected due to most needed force measures like lockdowns and manpower absenteeism because of health issues. On and above this, there has been an increase in prices of commodities like metals and plastics. All this has affected the costing. Hence, it …

Measurement of phase/phase-to-phase voltage & line current using single voltmeter and ammeter

Overview In most of the industrial applications, electricity is distributed in three phases i.e. R-Y-B (L1-L2-L3) system. Heavy industrial loads like motors, air compressors, work on three phase supply; Thus, electrical control panels are installed for controlling and monitoring of the electrical parameters of the system. In these panels, analog meters are generally deployed for …

DC Shunt used for high current measurement in Transformer Rectifier – Chlor Alkali plant

Overview Chlor-alkali plants produce chlorine and caustic soda. The most preferred method to produce chlorine and caustic soda is Membrane Cell Process. In this process, electrolysis takes place using metal anodes and metal cathodes partitioned by cat-ion exchange membranes. The electrolysis process is a direct current (DC) process, due to the nature of element connection …

Provide accurate electrical energy consumption at 400 Hz frequency for Airport gates

The Problem Aircraft operate on a 400 Hz Electrical Supply for many technical reasons. 400Hz majorly helps have lighter transformer cores on the aircraft thus reducing the aircraft weight and additionally lowers the energy stored in the transformer core which are among other reasons for the using higher frequency. Traditionally, aircraft ran their APU or …

Frictionless taut-band meters for high shock environments

Overview Metering industry is dominated by jewel pivot meters since the early use in D’Arsonval galvanometers. Such instruments have a low life in high vibration and shock conditions. The D’Arsonval design has since been perfected by many afterwards and it still continues till today, but a major innovation in 1950’s with the introduction of the …

Reducing shutdown time in process industries using Split core current transformers

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 …
