How to Calculate Burden for PTs The process for PTs is similar, but PT burden is typically expressed in VA. Use the formula: Determine Secondary Voltage (V): This is the PT’s rated secondary voltage (e.g., 120V). Calculate Total Resistance (R): Sum the impedances in the PT’s seco...
Figure 4depicts the resulting control scheme. After using Equation 2 to calculate dFF, it is then added to the traditional average current-mode control output (dI). You could then use the final duty ratio (d) to generate a PWM waveform to control PFC. Figure 4Average current-mode control ...
The amount of current consumed by each section can be used to calculate the approximate heat generated. Through your analysis, if the digital section with the microcontroller generates more heat, you can implement forced convection using a fan or provide vents nearby for the airflow. Using vents ...
Do not add the DLE and ILE together to calculate the maximum error that may occur at any digital step. The maximum error values specified in the device datasheet are the worst error values measured in a laboratory test environment over the given voltage and temperature range (refer to...
The next step in pseudo-label generation is to calculate the optical flow using recurrent all-pairs field transforms (RAFT) [74]. However, optical flow is frequently inaccurate at object boundaries, so we want our segmentation to be accurate exactly at these borders. Therefore, we consider video...

The following sequence is used to calculate RH: 1. First true RH during calibration: H0_rH_x2 setRH0 = H0_rH_x2 2 2. Second true RH during calibration: H1_rH_x2 setRH1 = H0_rH_x2 2 3. First raw H output during calibration: H0_T0_OUT set...
By convention the sum of the first ten harmonics are used to calculate THD (so, “total” = 10). There are other types of distortion such as intermodulation distortion (IMD) that happens when two different signals are distorted to create non-harmonic terms but those are...
There is no “one-size-fits-all” answer to the question of which inverter generator is best for you. It really does depend on your use case. Here are the essential factors to consider before making a purchase decision. AC Output:Calculate the totalstarting and running wattageof all the ap...
indistinguishable. The basic qualities we evaluate first are those of frequency response, linearity and THD [Total Harmonic Distortion]. Phenomena considered to be side‑effects, such as noise and hum, have a critical effect on how a signal sounds, [so] we do our best to make these match....
