Sistem Energimeter Moving, Braking dan Registering

A. Moving System Moving system adalah sistem mekanisasi pada energimeter yang terdiri dari piringan atau cakram tipis terbuat dari alumunium terpasang pada spindle dan diletakkan pada celah udara antara series magnet dan shunt magnet, sehingga akan diinduksikan eddy current pada piringan alumunium tersebut. Karena medan magnet yang dibangkitkan pada series magnet dan pada shunt magnet berbeda fasa 90 derajat, maka ...

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 ...

Ampermeter Design

When a D’Arsonval meter coupled with a parallel prisoners who serves as prisoners shunt it will transform into a d’Arsonval movement ampermeter direct current, as shown in Figure 6:18. When the current to be measured by the great ampermeter will require an inmate to drain excess so that the flow of current flowing to the coils of rotation remains small. ...

Changes Limits Measure

To raise the prisoners in the meter, Rm meter in front of prisoners are often added to the series prisoners Rv. So the prisoners in the new meter becomes larger, namely (Rm + Rv) .Tahanan parallel Rp remain energized Ip, while the current through (Rm + Rv) of Lev. Figure 6:20 Prisoners Shunt (Parallel) Equation custody parallel Rp can be ...

Voltage Measurements

As in the current measurement, measurement of electrical voltage with a voltmeter also has limitations, prisoner in Rm meter measuring limit voltage limiting capability. Raising the voltage measurement performed by placing detainees at the meter base ser Rs. Prisoners energized Rs series of Is, which flows through the meter for Im Rm. design Voltmeter When a D’Arsonval meter coupled with ...
