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 …

Spindle motor safety of Dope Winder in Textile Industry using Programmable Digital Meter N30H

Overview Textile sector is the largest single industry in India (and amongst the biggest in the world), accounting for about 20% of the total industrial production. This industry consists of manufacturing of various product ranges such as polyester and nylon yarns, woven and printed fabric, etc. An essential element in manufacturing these products is the …

Monitoring parameters in substation at remote locations using LM1360 with GSM

Overview There is no comfort like being in command. In the power system utility, monitoring is a key-tool for utilities in order to shift from corrective or time-based maintenance strategies to predictive maintenance, especially for switchyards located at remote locations. The substation monitoring device described in this note meets the requirements of engineering teams by …

Monitoring individual feeders in Distribution Panels using Multi Load Monitor – ML 1400

Overview From past to present, the needs and technologies have shifted. Substation may not have always been metered directly in the past for every individual feeder, except for critical loads. But over the years, technology and engineering requirements have changed rapidly, thus increasing the network of critical loads.  As the need for increased amounts of …

Measurement of Contactor coil resistance using Rish Con TPT

Overview In electrical systems and various industrial applications, contactors are used to remotely switch electrical power. The coil-actuated switch operates exactly like a relay, but a contactor typically handles higher amperes in the switch mechanism itself. The contactor coils are designed to be able to cope with continuous duty. Typically the contacts, two each to …

Temperature and Humidity monitoring in Cooling Ducts using P18D

Overview In large & closed commercial buildings such as shopping malls, hospitals, multi-storey offices etc. for effective cooling, ducts are installed. Measuring & monitoring these climatic parameters is essential. This serves in maintaining the environmental parameters circulated by the cooling duct. For this purpose, a transducer is installed for the monitoring of parameters at the …
