Overview

Dear All,Welcome to the course of understanding schematics of "Motor Control Circuits". This course covers from very basic concept of drawings / schematics. Training start with explaining the devices used in schematics, auxiliary relay, contactor, timer, etc. It is ensured that anyone with minimum to no experience in schematics learning can learn and master the skill. Trainer Introduction:Your trainer brings over 21 years of experience in operation & maintenance, erection, testing, project management, consultancy, supervision, substation automation, SCADA, and commissioning. With a background spanning power plants, high voltage substations, and HVDC installations, he has worked with renowned organizations such as Siemens Saudi Arabia. He has been involved in over 20 high-voltage substation projects across Pakistan and Saudi Arabia.His expertise encompasses a wide range of areas including protection systems, substation automation systems, design, testing, and commissioning of power generation systems, high voltage switchgear, protection relays, and control schemes. He has a proven track record of leading testing and commissioning teams for implementing electrical infrastructure projects for industrial clients, including steel and petrochemical industries.Topics covered in this training are as follows, Understand basics of SchematicsAuxiliary RelaysNO & NC Contact of RelaysContactorsPower & Aux contacts of contactorsDifference between Contactor & Aux RelaysSimulation of Aux & ContactorEarly Make, Late Break ContactsBreak Before Make & Make Before Break ContactsTimer , On Delay & Off DelayMCB and Its functionStatus of different components on drawingUnderstand Seal In / Latching / holding contactSimulate the Seal In contactDirect Online Starter circuitAdding start & stop indication to motor circuitMotor direction control circuitMotor & Power Control terminologiesBenefits of using Aux relay, contactorsContact bouncing & its effect on motor & how to avoid itAC Supply change over manual control circuitAC Supply change over automatic control with priority to Grid / GeneratorStar Delta Starter CircuitDahlander Motor ConnectionSequential Motor switchingSpeed control of two winding motorBest Regards
