Voltage regulation is a measure of how much an alternator's output voltage changes from no load to full load, expressed as a percentage. It is calculated by taking the difference between the no load voltage and full load voltage, dividing by the full load voltage, and multiplying by 100. The example shows an alternator whose voltage rises from 3300V at full load to 3350V at no load, resulting in a voltage regulation of 1.5% at unity power factor. The regulation depends on the load power factor.

1) The document discusses the effect of varying field excitation on two alternators sharing a load and an alternator connected to an infinite bus. It provides a numerical example of how the armature current, power factor, active power, and reactive power shared by two alternators changes when the field excitation of one alternator is adjusted. 2) An infinite bus is defined as a voltage source with zero impedance and infinite inertia that maintains a constant voltage and frequency regardless of load variations. When an alternator is connected to an infinite bus, any change in its field excitation will cause an armature current that helps regain synchronism. 3) For an alternator operating on an infinite bus, a change in field excitation will change the induced

This document discusses an alternator connected to an infinite bus. It defines an infinite bus as a constant voltage and frequency source that can absorb or supply reactive power without changing its characteristics. The document explains that at no load, an alternator synchronized to an infinite bus is in a floating condition where it delivers or absorbs no real or reactive power. It then describes what happens when the alternator's excitation is increased or decreased. An increase leads to reactive power delivery, while a decrease leads to reactive power absorption from the infinite bus, as the alternator's emf changes relative to the bus voltage. In both cases, an armature current is established to maintain the alternator's constant air-gap flux.

This document provides a summary of key concepts related to the operation of synchronous motors when load is varied:
1) Initially at no load, the synchronous motor is in a "floating" condition where no power is delivered or received from the supply.
2) As mechanical load increases, the rotor speed decreases, causing the rotor poles to lag the stator poles. This increases the load angle and armature current drawn.
3) Further increases in load angle cause the motor to operate at a lagging power factor, with active power input rising as sine of the load angle increases and reactive power drawn decreasing as cosine of the load angle decreases.

Working of cailing fan
The ceiling fan motor works on the principle of a single phase induction motor using a capacitor. It has a main winding and starting winding placed at right angles. The starting winding is connected in series with a capacitor and switch. When powered on, the capacitor produces a 90 degree phase difference between the windings, creating the rotating magnetic field needed to start the motor. Once up to speed, the starting winding is cut out and the motor runs as a normal single phase induction motor. A capacitor is used to split the single phase power into two phases to make the motor appear as if it has multiple phases of power, allowing it to generate a rotating magnetic field and operate.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

10.5.4 Voltage Regulation
- 3. (EnL - EfL) Percent of Regulation = X 100 EfL Where: EnL = The no-load terminal voltage EfL = The full-load terminal voltage of the generator.
- 4. For example, To calculate the percent of regulation of a generator with a no-load voltage of 462 volts and a full-load voltage of 440 volts
- 5. Given: No-load terminal voltage EnL = 462 V Full-load terminal voltage EfL = 440 V
- 6. (EnL - EfL) Percent of Regulation = X 100 EfL
- 7. (462V - 440V) Percent of Regulation = X 100 440V
- 8. 22V Percent of Regulation = X 100 440V
- 9. Percent of Regulation = 0.05 X 100 Regulation = 5%
- 10. Note: The lower the percent of regulation, the better the generator.
