How to Configure a Power System for High Current and Low Voltage Demands?

Click For Summary

Discussion Overview

The discussion revolves around configuring a power system for a furnace that requires very high current (approximately 50KAmps) at low voltage (around 100 volts). Participants explore various aspects of this configuration, including potential components like transformers and thyristors, as well as safety and regulatory considerations.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant seeks insights on configuring a power system for a high current, low voltage application, mentioning the use of a transformer with thyristors.
  • Another participant questions the experience of the original poster, asking about their background with similar systems and the regulatory requirements for such an industrial setup.
  • A third participant highlights the challenges of interrupting high currents and warns about the potential dangers, suggesting that this is not a suitable topic for an online forum.
  • One participant shares their current experience with a lower power supply and expresses a desire to understand the architecture of larger power systems, rather than building one themselves.
  • A suggestion is made to consult an engineering firm with relevant experience, emphasizing the complexity of designing a power controller for such high demands.
  • Another participant reiterates the need for licensed professionals to handle the design and implementation of high-power systems, indicating the risks involved.

Areas of Agreement / Disagreement

Participants express concern about the safety and complexity of configuring such high-power systems, with some advocating for professional assistance. However, there is no consensus on specific methods or approaches to take in the configuration process.

Contextual Notes

Participants mention the need for regulatory permits and inspections, as well as the importance of involving qualified electricians and engineers, but do not provide specific details on these requirements.

I have to configure a power system for a furnace which demands very high current of the order of 50KAmps with low voltage of the order of 100 volts.

Can anyone help me to get insight into how to configure the power system in boarder way.

I am planning to use a transformer with thyristors .

That's a lot of power to be dealing with for the first time, Jhon! How did you end up with this assignment if you have not worked with such systems in the past? What kind of systems have you worked with so far? What regulatory permits and inspections are required for this industrial system? What do you need to do with your company's insurance carrier to get the final system signed off?
 
Whoa! That is a huge current. In power plants, we use isolated phase bus ducts for half that much current.

Interrupting such currents is very difficult. If not done right, the fire and explosion can destroy the whole facility and kill people.

This is not a topic to ask strangers about on an Internet forum.

Well presently I am using a power supply with 3KAmps under 30 volts. So though I don't claim I have the expertise on power system but yes I am familiar with the stuff. Next I am just looking on the architecture not to build the power system. Thats why I just mentioned if anyone have knowledge of bigger power unit can reply. back.

My advice is to contact an engineering firm with the requisite experience. Your application is outside of mine, but a lot of detail work goes into building a successful 5 MVA power controller.

That is an enormous amount of electricity. Designing and working on such systems requires licensed electricians and electrical engineers. Please find qualified people to do this work for you. Thread locked.
