Basic terminology of electrical fault protection A new terminology for electrical currents now include all faults those between live conductors as well as earth or grounding faults. If we not design our circuit protection properly followed standard guide,it can cause serious injury or death for human and equipment damage. Fault current be determined at every [...]
What is electrical conduits? When we plan to do for electrical wiring,we need to use a conduit system to protect an electrical cable from damage due to mechanical or biological.It also make electrical wiring look nice and proper arrangement. As an electrician,a knowledge about conduits is important to decide which types are suitable for our [...]
When we want to setup the new building or application,it must have connection with electricity.So we need the electrical installation to make our application function properly and safety for human and equipment. Theoretically electrical installation is a variation of electrical devices installed to achieve specific purpose for any application.The key point that we must alert [...]
Circuit breaker specification for MSB. For circuit breakers specification MUST suitable with installation condition and needed.Main switchboard is the main power supply distribution for factory or building.This unit is a key for entire electrical power supply distribution. It feed the high volume of voltage for all equipment and machine.It also have a high value of [...]
What is types for power factor capacitor installation? Last time i already discuss about how to sizing the power factor capacitor.After we got a figure and corrected size for capacitor,the next step is what is types for installation of capacitor? The installation of power factor capacitor have several method that commonly used around the world.This [...]
Important of circuit breaker maintenance The circuit breaker maintenance is very important and it must added in periodical maintenance schedule.Why it so important?It is because of their importance for routine switching and for equipment protection and person. Production will stop if circuit breaker fails to operate because of a lack of preventive maintenance.The cost will [...]
When we design or build a electrical installation,we must know how to choose the suitable circuit breaker for the any application that we design.For electrician,this is compulsory knowledge.So here i want share my little knowledge about circuit breaker sizing method. This calculation for sizing the miniature circuit breaker.For other circuit breaker likes MCCB,ACB,VCB,OCB and etc,it [...]
MCB (Miniature Circuit Breaker ( BS 3871 ) is a mechanical device operate automatic operation designed to connect and disconnect the electrical circuit in the ordinary and extraordinary situation.Suitable for AC and DC voltage.It mean main function is to protected equipment or circuit from overload and short circuit. The size of MCB is small and [...]
