PDF Editor FAQ
What is the difference in a 1 uF 250V capacitor and a 1uF 400V capacitor?
The maximum voltage that can be applied across the capacitor depends on the dielectric that has been used in it and its thickness. Every dielectric breaks down at a certain electric field. For a parallel plate cap, as dielectric thickness increases the max. voltage that can be applied across it increases linearlyYou can use 250V rated capacitor for voltages upto 250V and 400V capacitor for voltages upto 400V. However, I recommend you use cap with rated voltage that is 2x the expected voltage across it.Capacitance of a 100V rated 1uF ceramic cap may drop to 0.1uF when biased with 100V :DThen again due to transients in the circuit, the capacitor voltage may exceed 100V. So for a Vo dc voltage application, as a rule of thumb use 2*Vo rated cap.
What is switching impulse voltage?
As far as I know, Overvoltages during switching are called surges and not impulse . Impulse voltage is a term reserved for the voltage spikes generated by lightning strikes on nearby systems. I will explain both of them below to address your query .Switching Overvoltages - As you might be aware, pure resistive sources and loads exist only in theory . Practically all of them have a inductive part in it which makes their power factor lagging. Whenever you switch on a load, a high magnetizing current is drawn instantaneously. Thus a high back emf is generated to the tune of L x di/dt which causes a overvoltage. As you may know, voltage leads current by 90 deg in a inductor . Hence, at zero current, voltage is at its peak . Switching at this point results in almost double overvoltage also known as flux doubling. Most of the devices are designed with this consideration. A test called as power frequency test (also known as HV test) is carried out to check the design suitability. The value defined for various voltage levels as below : a) 400V - 2kV . b) 11kV - 28kV. c) 22kV - 50kV . 4) 33kV - 70kVLightning Impulse Voltage - It is generated due to lightning strikes nearby the equipment. Though the value of spike can be very high, it has a very short duration of microseconds. Equipment are also designed considering this aspect and a test called Impulse withstand test is carried out to check the suitability . The values for various voltage levels are as below : a) 400V - 8kVp . b) 11kV - 75kVp. c) 22kV- 105 kVp . d) 33kV- 170kVp
What is phase voltage and what is line voltage?
The phase voltage and line voltage terms are used in 3 phase power systems. In a 3 phase 4 line power systems the lines are R (Red), Y (Yellow), B (Blue) and N (Neutral). Voltage (potential difference) between the lines namely R & Y, Y & B or B & R is called ‘Line Voltage’ while the Voltage between R & N, Y & N or B & N is called ‘Phase Voltage’. In a balanced 3 phase, 4 wire, 400V power system the Phase voltage will be 230V while the line voltage will be 400V.
