What is a synchroscope?
Sychroscope is a tool used to create phase angle synchronization and frequency between the AC power supply (AC). This is a critical safety measure when energy networks or generator outputs are merged or connected together. Synchroscopes are available in two basic formats: electromechanical and electronic. Electromechanical tools use a set of contradictory static windings and rotor to provide a dial -type indication. Electronic synchroscopes use the microprocessor to calculate and indicate the input state via the digital diode display (LED) emitting light (LED).
AC power voltage consists of a smooth sinus wave alternating between positive and negative peak values. The peak values are known as the supply amplitude; The number of times cycle per second is known as a frequency. When two sources of power supply are compared with similar amplitude or tension, they are considered “in the phase” when Both reachesNot positive and negative points of peak at the same time. When combining the AC power supply, it is important to ensure that both are the same voltage, frequencies and in the perfect phase. Connection of consumer current, if not balanced in this way, can lead to serious network damage.
AC power supply voltage is generally relatively stable and easy to indicate with a conventional device. However, the phase angle and the frequency relationship between supplies are rarely balanced without some modification. When combined by a generator or network needs, the synchroscope indicates any differences between them. If there are irregularities, the generator speed can be adjusted until the synchroscope indicates the perfect balance. At this point, supplies can be safely combined.
There are two basic types of synchroscope. The first is ElectromechanityP Cal, which denotes phase and frequency relations with indicator and indicator dialing. This tool is similar to an electric motor. It has a set of static stator windings against 90 degrees, polarizing coil and a rotor element that controls an indicator needle. One power supply is connected to the stator winding and the other to the polarizing coil. If the phase and frequency of two supplies differ, the rotor turns and indicates the difference.
The second type of tool is an electronic synchroscope. This type uses a microprocessor designed for sampling and comparing two alternating sources for phase and frequency characteristics. Any differences between them are then calculated and are listed either on the digital display of digital liquid crystals (LCD) or using LEDs. The second -type synchroscope usually has a circle of LEDs on its front panel.
