Motor capacitor run basic operation is same with motor capacitor start that use a capacitor to generate the current pulse and create the electromagnetic field for the winding to push a rotor to turn around. Normally capacitor for this motor made from polypropylene film capacitors material and it can running continuous without any problem.Run capacitor rated [...]
It is a single phase motors are widely used in electrical appliances such as washing machines, some compressors,vacuum cleaner, table drill, pump, etc. Why it become a common use? because it has advantages : Good Starting Torque Moderate Efficiency Moderate Cost it usually has a power rating from 1/20th to ¾ Hp, available to 1.5 [...]
It is the method to jointing and two of cable or conductor with a good quality and safe for electrical application.In electrical work, the connection cable is quite important and should be taken seriously, if it is the wrong way, this will lead to an accident or damage to the circuit. In industry,it have several [...]
Grounding or Earthing system is a connection system between metal and ground from the installation of electrical wiring.It is for provide easy access to a low impedance, or resistance to earthing protection system to operate effectively to ensure the safety of people or users from shock hazards electricity in the event of leakage current to [...]
When we need to perform Earthing or grounding resistance measurement,the important equipment that we must have is the Earthing resistance tester. We can found many types and brand of Earthing resistance tester in the market.It’s depend on our budget,requirement and application on actual work site.We need to ensure this device must always calibrated to get [...]
Why we need to perform insulation resistance tester?This test is strongly recommended to prevent electrical shock for equipment,electric motor or electric cable.We also can determine any abnormal condition or leakage before installation and can rectify the problem. Insulation resistance tester is the one of important equipment/meter for determining the resistance of the insulation in motor [...]
Socket outlet is used more widely in the home or industry to connect the electrical power to the equipment or appliances.We can found many types of socket outlet with nominal voltage rated for single and three phase. Before we install any types of socket outlet,please calculate the full load ampere and make sure the socket [...]
