Franck-Hertz Apparatus Sagitta
The requirements of an excitation system include reliability under all conditions of service, a simplicity of control, This part of the process is conducted using a specific excitation voltage, usually 10 volts. Operating at an excitation voltage that is higher than the calibration voltage can upset the temperature compensation. The effect on the calibration accuracy is minimal when operating at a reduced excitation Voltage. 2010-11-01 2020-10-26 2006-02-09 Look at the excitation graph (not shown) the excitation current I e for 10.7V of secondary excitation voltage is approximately 0.22A. Total primary current=(60A+20*0.22A) =64.4A Thus, the relay will operate if the primary current is 64.4A instead of the case with … 2019-06-12 This high current and voltage are compared and MW signal will be generated; This rise and drop in current and voltage will be sensed by AVR through CT/PT situated at generator output bus bars, so AVR maintains rated voltage by giving more/less excitation to AC exciter.

IDENTIFIERS-- c :. COSATI. Oct 6, 2016 Bonded, electrical resistance strain gage sensors require an excitation voltage for operation. The voltage drop across the gage resistance is L&S Electric offers an Advanced Excitation System (LS-AES). Current or Field Voltage regulation (manual) control mode; Rotating Exciter Diode Monitoring Wiith our partnering with Reivax, we are proud to offer the state-of-art RTX excitation system/voltage regulator (AVR) for full range of power generator.

A shift in the zero measurand output voltage (ZMO) will also decrease as excitation voltage is decreased. The excitation current is supplied to the rotor through a device called Automatic Voltage Regulator (AVR). The source of the excitation current varies from manufacturer and from different design. In some cases, the excitation current would be supplied from an external battery or generator.

Therefore it's marginal at best. Did you measure actual excitation voltage you get? Try powering the circuit from 15V. The voltage from the excitation winding is about 20 volts.
Varying the field is going to vary the DC output voltage, rpm will also affect the output, do you intend to

Note that with a 2.5V excitation, you'll be giving up 12dB of SNR. In your application, I'd stick with the lower excitation voltage. A boost converter will add noise that may be difficult to Compliance with a strain gauge's maximum permissible bridge excitation voltage is essential to avoid measurement errors. This webinar explains what this value means and how it is calculated. Topics included, inter alia: Strain gauges as heating elements; Calculation of the maximum permissible bridge excitation voltage 2019-07-24 2014-02-22 Excitation System Ceiling Voltage.
