Discussion Overview

The discussion focuses on identifying suitable sensors for detecting fault current in high voltage (HV) and medium voltage (MV) power lines, as well as exploring methods for transmitting fault information to a monitoring system. The scope includes technical specifications for sensors, communication devices, and integration with SMS technology.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • Maheel seeks advice on sensors for detecting fault current, specifically asking about options such as Hall sensors and clip-on type current transformers (CTs).
  • There is a request for recommendations on suitable radio devices to transmit signals from the sensor to a pole-mounted unit.
  • Maheel also inquires about methods to convert radio signals into SMS notifications.
  • Participants express appreciation for contributions from Jim Hardy, highlighting his extensive knowledge and practical insights.
  • Jim Hardy acknowledges the kindness of the community and emphasizes the value of practical contributions in understanding complex topics.

Areas of Agreement / Disagreement

The discussion does not present a consensus on specific sensor types or communication methods, as it primarily consists of inquiries and expressions of appreciation rather than definitive answers or solutions.

Contextual Notes

The discussion lacks detailed technical specifications or established criteria for sensor selection and communication methods. There are no resolved mathematical or technical steps provided.

Hi,
I'm working on a project to make a fault locating system on HV and MV (11kv to 220kv, 33kv first).
I'm try to make a device that can be directly mounted to the line (Mount on live bare conductors) to detect the fault in the power line and send a radio signal to devise mounted on the pole. Then the device mounted in the pole should send the signal (SMS) to mobile or a PC through GSM modem.
I'm interested in Electronic but not a expert. These are the my tasks,

1.Find a sensor to detect the fault (fault current),
What kind of sensor that can i used to detect fault current in the line? (hall sensor, Clip on type CTs...Etc)

2.suitable radio devices to send the radio signal to pole mounted unit?
3.how to convert radio signal to SMS?

any advice would be really appreciate...

Thanks...
Maheel

You guys are way too kind.


That my academic weakness is tolerated here says a lot of good about you folks.
If i can occasionally help with practical side of things , well, maybe it'll help somebody struggle up the learning curve as we all did.
Mathematician GH Hardy said to effect" There are students who simply cannot grasp higher mathematics. They should not be dismissed because they can contribute at a practical level."

Thanks guys, for letting me play here. When i blunder please correct me.
