Measuring Iron Play

Rotary iron measuring instrument (moving iron) have a different anatomy with swivel coil. Construction measuring tools iron swivel consists of six parts, namely (1) coils, (2) the iron core can rotate freely on the shaft, (3) shaft, (4) the pointer, (5) scale measuring, and (6) the spring , Rotary iron measuring instrument is a measuring tool of electrical quantities that ...

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 ...

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: ...

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 ...

Protection and Earthing Motor Loads

Motor operation protects against tampering and damage, on the applied control circuit protection equipment such as table 1. Reliability performance protection will determine motor protection against interference. As an illustration dipelihatkan in Figure 3-1, a circuit controlling a motor with two speeds and two-way swivel that is equipped with the tools and the TOL protection fuse or MCB. Figure 3-1. ...
