When do we use IFC?
Inferential current (IFC) Developed in the 1950s, IFC is most commonly used for pain relief (Kitchen, 2001). IFC is also claimed to reduce inflammation, and assist tissue repair (including bone fractures), and reeducate muscle (especially with incontinence).
Why is high resistance grounding important?
High-resistance grounding can be useful in power systems supplying critical processes that cannot suddenly stop. HRG also reduces the electrodynamic stresses on materials, the induced voltages on telecommunication lines, and the thermal deterioration of electrical circuits and equipment.
How many distribution transformers are used in a third arrangement?
The third arrangement involves grounding through three distribution transformers, connected star-delta to the substation busbar, and a resistor inserted in the secondary broken delta. Some calculations are the same as method one. We'll focus on the additional calculations. See Figure 8.
How often should I use high frequency?
How often can you use high frequency? You can use it every day but you don’t have to. I mainly use mine when I feel a zit coming, or I have one I want to go away quickly. If you want to use it for anti-aging then you need to use it daily.
Why is high frequency not negative?
High frequency utilizes oscillating current and the rate of speed is so high the device doesn’t have polarity so it’s not negative or positive this means that it can’t cause the chemical reaction that’s needed to “help products penetrate deeper”. This is why it doesn’t make a difference if you use it with products.
What does high frequency feel like?
High frequency feels like a little electric shock- if you’ve ever licked a battery it’s similar to that but more zappy. Use whatever level feels comfortable. Turning it up on full blast isn’t necessary- you want to feel the electricity but it doesn’t need to hurt to work.
Can you use botox with high frequency?
Can you use high frequency with botox or fillers-. Yes. I have botox and filler and have never had any issues with it moving them or making the results go away faster. I would wait for at least 24 hours after you get them done to use the device though.
Is high frequency good for acne?
High frequency is one of the best and most underrated skincare tools out there. I’ve been using it for 13 years because it helps my acne spots go away fast! But it also has other benefits.
What is high frequency treatment?
High-frequency treatments are meant to kill bacteria and reduce inflammation, hence the apparent acne-fighting benefits. The remedies increase circulation to stimulate collagen, making the treatment an effective anti-aging and glow-boosting tool, too. 1.
How to prepare for a high frequency facial?
How to Prepare for a High-Frequency Facial. For an at-home treatment, professional esthetician Kerry Benjamin says to always cleanse the skin before the facial. "Apply a layer of StackedSkincare EGF Serum to penetrate deeper into the skin to speed up acne healing," she adds.
Does Benjamin recommend high frequency?
Benjamin does not recommend high-frequency for people with a pacemaker, a history of heart disease, or during pregnancy. "If you have sensitive skin conditions such as rosacea, eczema, or psoriasis, please avoid these areas if they are inflamed.".
What Is The HRG Method?
Where Is The HRG Method used?
- HRG has uses in the electrical industry and in commercial and industrial applications. The main usages are in industrial processes where continuity of service is vital, as is the protection of rotating equipment, like motors and generators. The resistor reduces iron burning damage, damp out oscillations, and confines transient overvoltages to less than two-and-a-half times the stand…
Installing HRG According to The Nec
- Electrical installations governed by the National Electrical Code (The NEC), must meet Sections 250-36 and 250-187. Section 250.36 allows the use of high-impedance grounded neutrals (usually a resistor) in three-phase AC systems of 480V to 1000V meeting the following requirements: (1) Only qualified persons service the installation (2) Equipped with ground detectors (3) No line-to-…
Design Considerations For HRG
- The common practice to achieve HRG's goals is to select a resistance value to allow a single line-to-ground fault current through the resistor equal to or slightly higher than the capacitive charging current of the system. To reach this condition, use a value of resistance equivalent or somewhat less than the capacitive reactance to ground. This procedure balances two conflicting requirem…
Components of An HRG Package
- Some manufacturers produce packaged HRG systems. Depending on the user’s needs and budget, these packages include a grounding resistor, a ground-fault detector and relay, visual indicators, optical arc-flash detection sensor, fault-tracking system, and a grounding transformer to provide a neutral on ungrounded systems. They are for use in low- and medium-voltage powe…
Calculations with The Method of Symmetrical Components
- Figure 1 shows a simplified circuit diagram with the connection between the sequence networks and the current distribution for a single line-to-ground fault. In a previous article focusing on the Peterson coil method, we confirmed that only the zero-sequence network is significant when the ground-fault current goes back to the source through the natural distributed capacitance of the …
Where Should The Resistor Be placed?
- There are three typical arrangements for resistor placement. The first arrangement is the easiest way to get neutral. It involves using the neutral of a wye-connected power transformer or generator. The resistor will be placed directly in the neutral. This method is appropriate for new systems rated 5kV or less. The second arrangement employs one distribution transformer in th…
An Example Using The Three HRG Arrangements

A 13.8kV industrial power distribution grid has a total charging capacitance to ground (calculated with tables) of 0.658 microfarad/phase. At a rated-frequency of 60Hz and neglecting the transformer zero-sequence impedance, calculate: 1. Zero-sequence capacitive re…
Favorable Performance Traits and Drawbacks
- HRG limits the first ground-fault current to a value that will not trip the faulted circuit instantly but will sound an alarm (sound and visual) to alert maintenance personnel. Hopefully, this results in a safe, planned shutdown. In addition to improving availability, an advantage over the ungrounded method is that the system will not be subject to destructive transient overvoltages that may cau…
Areas of Application
- Use HRG in processes requiring continuity of power and when converting ungrounded systems to improve their performance (primarily fault damage and transient overvoltages), placing special attention to ground relaying. Also, apply HRG in generator-transformer unit systems, to prevent burning damage caused by the ground-fault current, and in utility station auxiliaries. In systems r…
