What is the excitation?The main purpose of excitation system for generator is to supply the power source to the rotor field coil.Excitation system produce the field current and it controlled by the automatic voltage regulator (AVR).I already discuss about automatic voltage regulator on my last post. This field current controller is important to ensure the [...]
Motor protection is the one of important criteria that we must consider when design the application to avoid serious damage or injury. Normally we used thermal overload relay to protect electric motor from overload current problem.But if we used soft starter to driven our motor application,the suitable types of protection is using the motor thermal [...]
Star Delta starter is the most widely used application especially for Air-compressor and HVAC system.This starter used for 6 or 12 wire for motor terminal depend on electric motor that chosen for the application. Basically this starter used 3 unit contactor,1 unit timer delay,1 unit overload relay and start/stop button to control the star delta [...]
Before we make a decision to install Molded case circuit breaker for our application,firstly we need to know about types of MCCB.It important information that we must know to make sure our MCCB can functioning properly to protect our application from electrical failure. As we know the main function of MCCB are to protect our [...]
Circuit breaker is the one of important protection device when installing of electrical induction motor.This time i want shared some information about the major parameter that we need consider when applying Molded case circuit breaker(MCCB) for electric motor. If we not selected the right MCCB for our electric motor application,it will effected to the system [...]
Cable termination is important when we install equipment,machine,induction motor,power supply distribution and many more.We use a cable lug to connect the electrical cable with terminal or busbar. The right method to install cable lug is important to ensure the termination is perfect and tight to avoid sparking.It can cause the damage of cable or the [...]
Cable is a important thing in electrical engineering to transfer the power supply from distribution to end user or equipment.It must have a quality and durability to ensure it can stand for any condition and long life span. Day by day,manufacture made the research and development to improved quality and design of cable suitable with [...]
