Power Factor improvement Methods with Their advantages & Disadvantages Methods for Power Factor Improvement The following devices and equipment are used for Power Factor Improvement. 1. Static Capacitor 2. Synchronous Condenser 3. Phase Advancer 1. Static Capacitor We know that most of the industries and power system loads are inductive that take lagging current which decrease the system power factor (See Disadvantages of Low Power factor) . For Power factor improvement purpose, Static capacitors are connected in parallel with those devices which work on low power factor. These static capacitors provides leading current which neutralize (totally or approximately) the lagging inductive component of load current (i.e. leading component neutralize or eliminate the lagging component of load current) thus power factor of the load circuit is improved. These capacitors are ...
What is UPS? -Working & Types of UPS Explained This article explains the UPS, its application, historical background, types and working principle of UPS with their schematic diagram. Definition: A UPS is a device which provides an uninterruptable power supply so as to maintain the continuity of supply in case of power outage. UPS stands for Uninterruptable Power Supply. Requirement of UPS: There are several applications where even a temporary power failure can cause a great deal of public inconvenience leading to large economic losses. Examples of such applications are major computer installations, process control in chemical plant, safety monitors, general communication systems, hospital intensive care units (ICUs) etc. For such critical loads, it is of paramount importance to provide an uninterruptable power supply. Here, comes the importance of UPS. Application of UPS system caters to such critical loads. Background: UPS system used earlier were base...
