In general, the water pump machine used in households is a centrifugal water pump type driven by a 1-phase permanent-split-capacitor induction motor or abbreviated as PSC motor. In the use of driving a water pump using solar power, a 3-phase cage rotor induction motor must be driven by a 3-phase alternating voltage. A 1-phase permanent-split-capacitor induction motor or abbreviated as PSC motor…
A power supply circuit that produces a lot of output is needed by electronic systems that work with several voltage levels. An example is a control circuit that controls a 3-phase inverter, where the control circuit uses several integrated circuits (IC) which must be supplied by a power supply. isolated from one another. The power supply circuit that will be made gets power input from solar pan…
A three-phase induction motor is a type of AC (Alternating Current) motor that is input by alternating current. When driving a water pump using solar power, a 3-phase cage rotor induction motor must be driven by a 3-phase alternating electric voltage. For this purpose, a power converter is needed which will convert the direct electricity produced by the solar panels into 3-phase alternating ele…
Power transformers have common problems such as thermal and electrical failures which can produce harmful gases in the insulating oil which is commonly known as fault gas. For this reason, transformer care and maintenance is required by testing the transformer oil, namely DGA (Dissolved Gas Analysis) testing. The aim of this research was to detect transformer failures and analyze the relationsh…
Continuity of electrical energy in an electrical system must be protected by a protection system with the right settings. Over current relay is one of the protection systems that is always used.
