This section covers what is meter tampering, why is this a problem for utility providers, and some common ways a meter is tampered.
This video will cover the first section of the training module that provides an overview of supply voltage supervisors. We will start with a brief introduction to Supply Voltage Supervisors. Next, we will present some system level design challenges that can be solved using the Supply Voltage Supervisors and end the presentation with information on finding the right collateral and resources for further help.
Leakage current detection is necessary in most of the industrial and residential breakers as well as in many EEQ such as EV chargers, PV inverters etc. In this course we’ll deep dive into circuit breakers and review TIDA-010041 reference design that provides an easy and efficient method of detecting residual current or ground fault by leveraging voltage supervisor IC. This solution also finds application in over-voltage detection in binary input module EEQ. In addition, this also includes power sequencing using supply voltage supervisors.
The first line of defense against tampering by bypassing current, reversing connections, and disconnecting leads is the meter case. Due to this, it is common for utilities to require some form of intrusion detection system to detect when someone opens a case. In this section, we will cover how to detect someone trying to open the case of a meter.
For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions. Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.
