1. ### Current dependant load switch, cant solve it passively?

Hey there, i couldn’t fall asleep trying to solve following scenario: i have two power supplies running 24vdc in parallel, a main and one supplemental power supply. Both are being filtered with capacitors before supplying a single load. Now if one wants to run it, such that the supplemental...
2. ### Understanding active inrush current limiter

I came across this device and was interested in understanding its functionality, https://www.mouser.com/ProductDetail/MEAN-WELL/ICL-16R?qs=vLWxofP3U2wgD7jPA%2Bx9JQ== Could something like this work with an AC motor that has extremely high inrush current? I wasn't sure what the datasheet meant by...
3. ### Circuit Breaker Location

Hi, in IEEE 3 bus, why are circuit breakers connected at the 'load' rather than connected at the 'generator and load'?
4. ### Voltage Magnitude, Phases, Current for Bus (Load Flow)

Say there are 3 buses of: Bus 1: Slack bus with a voltage source of E=1.0 and phase of 0° Bus 2: a generator and a load. Bus 3: a load. The line impedance are given below: z12 = 0.05 + j0.1 z13 = 0.02 + j0.05 z23 = j0.05 z11 = -j100 z22 = infinity z33 = -j40 The generators and loads are given...
5. ### Given 3 buses with line impedance, generators and loads provided, where must the protection circuit be allocated?

The 3 buses are Bus 1: Slack bus with a voltage source of E=1.0 and phase of 0° Bus 2: a generator and a load. Bus 3: a load. The line impedance are given below: z12 = 0.05 + j0.1 z13 = 0.02 + j0.05 z23 = j0.05 z11 = -j100 z22 = infinity z33 = -j40 The generators and loads are given below...
6. ### How to calculate the current of a circuit if a resistor is placed with load in series?

Assume we provide a load with its rated voltage, suppose it should draw the current it need at such voltage level. However, what if we place an additional resistor in series with the load, can the load still draw the same current as it needed?
7. ### Two plants connected by a transmission line, load at plant 2, power loss included. Find the required generation for each plant and the power received

A system consists of two plants connected by a transmission line. The only load is located at plant 2. When 200 MW is transmitted from plant 1 to plant 2 power loss in the line is 16 MW. Find the required generation for each plant and the power received by the load when lambda for the system is...
8. ### Star-connected, 3-phase, synchronous generator with armature resistance, reactance, leakage resistance. Calculate rated load and unity power factor

If a 100 KVA star-connected 400 V three-phase, 60 Hz synchronous generator with armature resistance 0.35Ω/phase and 3.5Ω reactance and leakage resistance given is 1Ω/phase. Calculate at rated load and unity power factor at i) No load e.m.f ii) Internal e.m.f. iii) percentage of regulation at...
9. ### Using MOSFETs to control resistive loads

Hello everybody! I want to dump energy from some solar panels into heating by using two heating elements (R1 and R2). To maximize the power output from the solar panels I plan to use a microcontroller to change between single heater, series and parallel configurations. Now, I tried to come up...
