Volt-meter Function

Things to consider in measuring the voltage is switch positions and limit measure measuring range (range). If will measure 220 ACV, switch the measuring range must be in a position ACV, and limit measure (range) at number 250 ACV. The same applies to DC voltage measurement (DCV). Equally important to note is the safety factor. Note whether the cable wrapping ...

Measuring Variable Resistors

The variable resistor is a resistor that can change the value of the unit Ohm his manner twirling players lever or screw that moves the sliding contact / sweeper (wiper) contained in the resistor. See Figure 11. Figure 11. Variable Resistors The variable resistor has a lever players usually called potentiometer (potentiometer), and which has a screw regulator called preset ...

Measuring Capacitors and Diodes

a. Measuring Capacitors Capacitors are electronic components that are designed to be able to store and dispose of Unidirectional Voltage Power Lines (Direct Current Voltage / DCV). Capacitors are divided into two types. First, the capacitor has the anode (+) and negative (-). In the electronics technique called a polar capacitor (polarized capacitor). Second, the capacitor has no anode (+) ...

Measuring Transformer

The transformer is an electronic component that is designed to be able to move the Alternating Electric Current Voltage Feedback / Voltage Alternating Current (ACV) of the primary winding (P) to the secondary windings (S) with no direct relationship between the two coils. See figure 23. Figure 23. Transformer A transformer is still good and usable, or is damaged can ...

Measuring Transistor

Transistors are electronic components that are designed as a current amplifier, thereby transistor also called device (device) which handles current (current handling device). See figure 16. Figure 16. Transistor Judging from the type, the transistor is divided into two, namely the type PNP (Positive-Negatip- Positive) and type NPN (Negative-Positive-negative). Inlet (leads) to the transistor (commonly known as foot transistor) named ...

Prinsip Pengontrolan Motor Listrik

Kata kontrol berarti mengatur atau mengendalikan, jadi yang dimaksud dengan pengontrolan motor adalah pengaturan atau pengendalian motor mulai dari pengasutan, pengoperasian hingga motor itu berhenti. Maka pengontrolan motor dapat dikategorikan menjadi tiga bagian menurut fungsinya, yaitu: Pengontrolan pada saat pengasutan (starting) Pengontrolan pada saat motor dalam keadaan beroperasi (pengaturan kecepatan, pembalikan arah putaran dan lain-lain) Pengontrolan pada saat motor berhenti ...
