- What is AVR? Explain the function AVR? - ALLInterview
Answer sudheer AVR-means automatic voltage regulator AVR regulates the voltage of a generator when voltage drops, due to load increase, AVR gives voltage to exciter and exciter more xecites the alternator and voltage improve
- What is RTCC panel and why it is required - ALLInterview
Answer b c pandey RTCC means REMOTE TYPE TAP CHANGING CONTROL panel,it is used in transformer for tap changing It contains an AVR (Automatic voltage regulator),Relays and contactor for motor Is This Answer Correct ? 22 Yes 17 No 1 2 3 4 Post New Answer
- What is the working of AVR in AC generators? - ALLInterview
Answer s arunkumar AVR means Automatic Voltage Regulator There are different types of excitation in generators, AVR is used to regulate the voltage applied to the generator Because generator draw enoromous power from the source in order to regulate this AVR is used
- What is PMG and AREP excitation system in generator
What is PMG and AREP excitation system in generatorAnswer suryaa Electrical Power Output Sense Main Stator Exciter Stator Exciter Rotor Mechanical Rotational Power Input Diode Bridge Main Rotor Set Reference Output AVR Power Auxilliary Coils (Series and Shunt) to give constant power source AVR14 – AREP EXCITATION SYSTEM The AREP excitation system improves the voltage response of the
- What is RTCC panel and why it is required - ALLInterview
Answer bibinck RTCC means "Remote Tap Changer Control Cubicle" as the name suggests it is used for remote operation RTCC is used to raise lower the tap as and when required ,with the help of an AVR-automatic voltage regulator,remotely It also gives important indications about the transformer such as oil temp high, winding temp high , bucholz relay trip , coller fans on off It gives a
- what does the transformer connection symbol YNaod1 mean
Answer sujeet pandey you all people must be knowing about the symbols like YN and d1 but what about a0 The 'a' represents that is auto-transformer and 0 represents that there is 0 phase difference b w H V and I V (intermediate voltage) winding since both are star-star d1 means the transformer has a tertiary winding which is delta connected and this delta is lagging the H V winding by 30
- What is RTCC in a transfomer and specify its function.
Answer yash RTCC is Remote Tap Change Circuit is connected to OLTC of Transformer through control cables It raise lower the voltage as accordingly specified by controlling the motor drive in OLTC electrically (and manually through Push Buttons) In RTCC an AVR (Automatic Voltage Regulator)is fixed to maintain the output voltage level (raise lower) by controlling the motor
- 5. What is PMG in Alternators? - ALLInterview
Answer s madhavan The answer above is partially correct All AC alternators presently manufactured are brush less type with built in AVRs ( Automatic Voltage regultors ) Normally AVR get feed back from load for its regulation If the loads connected have excessive harmonic content, feed back to AVR get distorted and hence regulation gets affected To avoid this a PMG is mounted on the
