Ohmmeter Paralel

Dalam keadaan tidak dipergunakan, saklar S harus dibuka agar batere V tidak lekas menjadi lemah. Bila ohmmeter dipergunakan, maka saklar S ditutup.Mula-mula diambil RX = tak terhingga atau A-B dalam keadaan terbuka, sehingga diperoleh arus melalui M + IM. Pada keadaan ini pontensiometer R2 diatur agar arus melalui M mencapai harga maksimum (skala penuh), sehingga: Kedudukan R2 jangan diubah lagi ...

Magnet Contactor

Magnets or magnetic contactor switch is a switch that works by magnetism, meaning that the switch can work if there is a magnetic force. Magnet serves as towing and release contacts. A contactor must be able to drain and disconnect the electric current in normal circumstances. Electric current flowing normally is an electric current flowing during the termination does not ...

Single Phase Power Measurement

Measurement of power on the system backflow Janis power can be divided into three, namely – Apparent power (S) measured in VA or kVA – Active Power (P) which is measured in watts or kW – Reactive Power (Q) measured in VAR or kVAR The relationship between the three power can be explained easily by the power triangle, as follows: ...
