An earth tester, also known as a ground tester, is a device used to measure the electrical resistance of the earth or ground. The voltage of an earth tester can vary depending on the specific model and application, but here are some common voltage ranges:
*Common Voltage Ranges*
- *Low-Voltage Earth Testers*: 9-12 volts, typically battery-powered.
- *Medium-Voltage Earth Testers*: 100-500 volts, typically used for industrial and commercial applications.
- *High-Voltage Earth Testers*: 1000-5000 volts, typically used for high-voltage transmission and distribution systems.
*Specific Models*
- *Digital Earth Testers*: Typically 9-12 volts, battery-powered.
- *Analog Earth Testers*: Typically 100-500 volts.
- *Three-Phase Earth Testers*: Typically 100-500 volts
