Because the voltage on the primary winding is too high and the core gets saturated. When this happens the transformer effect cannot kep increasing the voltage on the secondary winding, clipping the output. Either reduce the voltage on the primary of get a oriented iron core with at least 10,000 gauss flux capacity.

What portion of the input signal is clipped at the output?
Christmas's
What type of signal at the NPN output?
A: It always a voltage since it is a voltage amplifier
Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
What is the output of the control transformer?
Depends on what the voltage is being stepped down in that particular control transformer. Control transformers usually step down a voltage of 480/208v to 120V. The 120Volts can now be used in safer manner to "control" start/stop buttons, and other components that are only built to run on 120V
What is the Effect of quiescent point close to cutoff?
The output voltage swing will not reach its maximum. This would then give clipping of one side of the signal which means the signal output is not a amplified representation of the original signal.

What is rtcc pannel?
RTCC (Remote tap changer control) panel is one of the LT panel which has microcontroller, contactors, relays etc it senses the fluctuation in distribution voltage (input of Transformer) & give signal to OLTC to change the voltage(Output of the transformer) to set a value

What will happen to the output ac signal if the dc level is insufficient?
What will happen to the output ac signal if the dc level is insufficient? Sketch the effect on the waveform.

What is meant by the term small signal amplifier?
Small signal amplifiers are generally referred to as "Voltage" amplifiers as they convert a small input voltage into a much larger output voltage.
What component develops the output signal in a common emitter amplifier?
The voltage drop across the emitter-collector junction develops the output signal with the help of a resistor or two in series. The output is 'seen' at the collector.
What is the Effect of quiescent point close to cutoff?
The output voltage swing will not reach its maximum. This would then give clipping of one side of the signal which means the signal output is not a amplified representation of the original signal.
What happen if the value of the dc supply is changed in amplitude modulation?
The rf output voltage should be proportional to the signal voltage in AM. A change in the DC supply voltage should also cause a proportional change to the rf output voltage.
Why transformer is not called an amplifier?
In an ideal transformer the power in equals the power out there is no gain. In an ideal amplifier the power out equals the Gain *Power In. An ideal transformer transforms energy at a ratio of its windings. For example an ideal 1:10 ratio transformer (step up) would convert a 10Volt input at 10amps to a 100Volt output at 1Amp. Or conversely an ideal 10:1 ratio transformer (step down) would convert a 10Volt 10Amp input into a 1Volt 100Amp output. Since Power = Voltage * Current we can see the power in equals the power out in an ideal transformer. In an ideal amplifier the power out is greater than the power in. This is defined as the gain of the amplifier. An ideal amplifier with a Voltage gain of 10 would take a 1Volt 1amp signal and amplify it into a 10Volt 1 amp signal. An ideal amplifier with a Current gain of 10 would take a 1Volt 1Amp signal and amplify it into a 1Volt 10 amp signal. Since Power = Voltage * current we can see the power in is less than the power out showing a gain in power.
What is peak detector?
a device which output voltage is almost the real peak valueof an applied signal
