This device can show if two systems are synchronized with each other! \u00a0In this article from Linquip, we will explain in detail the answer to \u201cwhat is Synchroscope?\u201d and talk about its structure and function in detail.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Synchroscope\"><\/span>What is Synchroscope?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A Synchroscope is a device designed specifically to indicate if two power networks or generators (or any other AC electrical power system) are synchronized with one another. This device checks the operation of both systems to make sure they are working at the same frequency. Plus, for them to be synchronized, the phase angle of these two systems should be 0 as well. The phase sequence between two poly-phase systems, too, should be the same. So a Synchroscope is responsible for measuring and indicating the phase angle and frequency difference between two desired power systems.<\/p>\n<p>This device plays a crucial role since the wrong number between the two aforementioned parameters causes severe damage to the systems that are not safely guarded by circuit breakers or fuses. This damage is due to the flow of high currents. These two numbers should be zero for the two AC power systems to be able to connect together or else, the systems are considered to be unsynchronized. A Synchroscope can also show the incoming alternator\u2019s speed and whether it runs slow or fast.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Synchroscope_structure_and_working_principles\"><\/span>Synchroscope structure and working principles<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A Synchroscope follows simple operating principles that you need to know of when searching for the answer to \u201cWhat is a synchroscope?\u201d The relative frequency difference, as well as the phase angle between two AC power systems, are measured with the help of these principles. A Synchroscope consists of a stator, a two-phase one, and a rotor. The two-phase supply to the Synchroscope is provided by the alternators.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-10410\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2.jpg\" alt=\"what is Synchroscope\" width=\"700\" height=\"525\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2-300x225.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2-696x522.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2-560x420.jpg 560w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2-80x60.jpg 80w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2-160x120.jpg 160w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-2-265x198.jpg 265w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>When two of the phases are synchronized together, the third one automatically follows the process and will sync with the other two phases. The Synchroscope\u2019s stator receives the supply from the existing alternator. The incoming alternator, then, provides the supply for the rotor. This phase shifting between the above-mentioned supplies is a sign of the difference in both frequency and phase to the connected alternators that are parallel to one another.<\/p>\n<p>When the alternators with different frequencies are connected together, the device starts operating to indicate the desired parameters. When the stator\u2019s and the rotor\u2019s frequency stay the same, the rotor won\u2019t rotate and the dials remain stationary. With a change in the supply\u2019s frequency of the rotor and the stator, the rotor starts moving and as a result, the dials start deflecting. The supply frequency\u2019s difference is the parameter that the rotor\u2019s speed depends on. The larger the difference, the higher the speed of the rotor. And when the difference is minimal, the rotation speed of the rotor reduces as well.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Different_Synchroscope_types\"><\/span>Different Synchroscope types<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Synchroscopes have two main types:<\/p>\n<ol>\n<li><strong>Electrodynamic type<\/strong><\/li>\n<li><strong>Moving Iron type<\/strong><\/li>\n<\/ol>\n<p>Now let\u2019s dive into these two types (Electrodynamic and moving iron type) to be able to learn more about \u201cWhat is Synchroscope?\u201d<\/p>\n<ul>\n<li>\n<h3>Electrodynamic Synchroscope<\/h3>\n<\/li>\n<\/ul>\n<p>This Synchroscope type is also known as the western Synchroscope type and includes an electrodynamic device as well as a three-limb transformer. The static and dynamic methods of synchronization have been brought together in this Synchroscope type to achieve the correct synchronization instant. In the dynamic method, an electrodynamometer-type Synchroscope will be used while in the static method, the system will need a lamp.<\/p>\n<p>The static part of the Electrodynamic Synchroscope, as we mentioned above for answering \u201cwhat is Synchroscope?\u201d, contains a three-limbed transformer. The central lamp is responsible for the lamb and the two outer ones are responsible for the busbar voltage and the incoming machine voltage.<\/p>\n<p>The central limb receives the fluxes made by the outer limbs. The phasor sum of the received fluxes becomes the next one in the central limb resulting in the operation of the lamp. The flux in the central limb makes the lamp grow to its highest level when the two voltages provided by the outer limb windings are in the same phase. This is exactly the opposite of when they are out of phase.<\/p>\n<p>The dynamic part contains an electrodynamometer-type Synchroscope. This part consists of two parts that have been divided into a fixed coil. The moving coil of this part contains a pointer. A resistor connects the fixed coil to the busbar and there\u2019s an inductor connected to it as well. The incoming machine\u2019s terminal is connected to the moving coil by a capacitor.<\/p>\n<p>When both voltages are in the same phase, then the two currents would be in quadrature to one another and no torque will impact the pointer and remains vertical. In this part, the movement of the pointer (whether it be clock-wise or counter-clock-wise) indicates the speed of the incoming machine.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-10411\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-1.jpg\" alt=\"what is Synchroscope\" width=\"700\" height=\"575\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-1.jpg 700w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-1-300x246.jpg 300w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-1-696x572.jpg 696w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-Synchroscope-1-511x420.jpg 511w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<ul>\n<li>\n<h3>Moving Iron Synchroscope<\/h3>\n<\/li>\n<\/ul>\n<p>If you want to know \u201cwhat is Synchroscope?\u201d then learning about the moving iron type would be the next step for you.
