Resonance and high frequency

This discovery of prof. Richard Vialle presented is amazingly similar

Probably I should record more videos of my experiments, since I found something really strange and might be somehow related to work of Vialle. Where I am getting more power using one coil with less voltage available comparing with 2 or more coils when voltage is much higher but current disappear ... in parallel coils

Actually there are 2 coils connected in reverse into the bridge rectifier, one where input from pancake coils goes to the pipe and pickup coil wrapped on it goes on ac side and second where earth connection goes into the pickup coil and the pipe output goes into other side of bridge rectifier.

It seems that adding another one or more on either side of bridge rectifier increase the voltage output but reduce the current available.

Using just 2 coils for each side of rectifier produce a strange effect: both ac and dc are available in output and I can measure them with a digital multimeter ... not sure how accurate is, this is why I only trust seeing a load doing the work. Why I am trying to get some measurements ? I am trying not to destroy all my loads.
Now, I am not sure anymore which (ac or dc) doing the work in loads tested as I don't have adequate loads and they are underpowered for the moment.

Anyone here is aware how meters for electric power grid works ? Do they load the grid or home grid when metering consumption ? How reactive power meters works ?

[kampen]

Yes! I can explain how electric power meters work in the grid and how they handle reactive power.

1. How Electric Power Meters Work in the Grid
Electricity meters measure the energy consumed by a household or business. There are two main types:

• Electromechanical meters (older, with a spinning disk)
• Digital smart meters (modern, with electronic sensing and communication)

The meter is installed between the utility grid and the home electrical system. When metering consumption, the grid does not get loaded by the meter itself. 
Instead, the meter is a passive monitoring device that tracks power flowing from the grid into the home.
2. Does the Meter Load the Grid or the Home Grid?
No, the meter does not add any significant load to either the grid or the home. It simply measures energy usage by sensing voltage and current flow. 
The small amount of power needed to operate the meter itself is negligible.
3. How Do Reactive Power Meters Work?
Reactive power (measured in kVAR, kilovolt-amperes reactive) is caused by inductive or capacitive loads, like motors, transformers, and fluorescent lighting.

• Traditional residential meters typically measure only real power (kWh), which is the actual power used.
• Commercial and industrial customers often have meters that also measure reactive power (kVARh). These meters:
  
  • Use current and voltage phase shift to determine reactive power.
  • Measure the difference between apparent power (kVA) and real power (kW).
  • Often help utilities charge extra fees for poor power factor (low efficiency due to high reactive power use).

Would you like details on Power Factor correction or how smart meters handle this?

Power Factor Correction (PFC) Explained

Power factor (PF) is a measure of how effectively electrical power is being used. It is the ratio of real power (kW) to apparent power (kVA) and is given by:
PF=Real Power (kW)Apparent Power (kVA)PF = \frac{\text{Real Power (kW)}}{\text{Apparent Power (kVA)}}
A power factor of 1.0 (or 100%) means all power is being effectively converted into useful work. 
A lower power factor (<1.0) means some power is wasted as reactive power (kVAR).
Why Correct Power Factor?

• Reduces electricity costs: Many utilities charge industrial customers a penalty for low power factor.
• Reduces strain on the grid: A low PF increases the current flow, leading to higher losses in transmission lines.
• Improves equipment efficiency: Poor PF can cause overheating and reduce the lifespan of electrical equipment.

How Power Factor Correction Works
Power factor correction (PFC) is done by adding capacitors or inductors to the electrical system. 
The goal is to counteract the reactive power caused by inductive loads (motors, transformers, fluorescent lighting, etc.).
Methods of Power Factor Correction

• Static Capacitors
  
  • Used for fixed loads with a consistent power factor issue.
  • Connected in parallel to supply leading reactive power to cancel out lagging inductive loads.
• Automatic Power Factor Correction (APFC) Panels
  
  • These use banks of capacitors controlled by relays.
  • The system automatically adjusts compensation based on load changes.
• Synchronous Condensers
  
  • Large rotating machines that generate or absorb reactive power as needed.
  • More common in large industrial applications.
• Active Power Factor Correction (APFC) Circuits
  
  • Used in electronics and power supplies to correct PF dynamically.
  • Found in high-efficiency switch-mode power supplies (SMPS).

Example: Industrial Power Factor Correction
If a factory runs a large motor with a power factor of 0.7, it means 30% of the power drawn is wasted as reactive power. 
By installing capacitors, the power factor can be improved to 0.95 or higher, reducing energy bills and system losses.
