Sensor Unit:

  • Hall Effect Sensors: These sensors, provided by us, are used to detect the magnetic field generated by the current flowing through the conductor. They are often placed around the conductors to sense the magnetic field changes caused by a ground fault.

Amplification Circuit:

  • Amplifiers: To amplify the weak signals from the Hall Effect sensors for better detection and analysis, We incorporates advanced amplification technology into our devices.

Microcontroller or Processor:

  • Microcontroller/Processor Unit: A central processing unit that manages and processes the signals from the sensors. GAO Tek’s microcontrollers implement algorithms to analyze the data and identify the location of the ground fault.

User Interface:

  • Display: An interface for users to visualize the information. This could be an LCD screen, LED indicators, or other display types provided by GAO Tek.
  • Control Buttons: Interface components for users to control and configure the GAO Tek device.

Communication Interface:

  • Serial Ports/USB Ports: To connect the device to external systems for data logging or further analysis.

Power Supply:

  • Battery or Power Supply: The device needs its power source, which can be a rechargeable battery or an external power supply.

 Algorithms/Software:

  • Ground Fault Detection Algorithm: Software that processes the signals from the sensors to detect the presence and location of ground faults. Our advanced algorithms ensure accurate and reliable ground fault detection.
  • Data Logging and Analysis Software: Some GAO Tek devices include software for data logging and further analysis on a computer.

Mechanical Components:

  • Enclosure: A protective casing to house and safeguard the electronic components from environmental factors. GAO Tek’s durable enclosures ensure the longevity and reliability of our devices.
  • Current Probes or Clamps: Mechanical components that facilitate the connection of our ground fault locator to the conductors for sensing current.

Safety Features:

  • Isolation and Insulation: Components and measures to ensure the safety of the operator and the device itself by isolating it from the electrical system.

Calibration and Adjustment Mechanisms:

  • Calibration Controls: Potentiometers or other mechanisms to calibrate and adjust the sensitivity of the GAO Tek ground fault locator.
