A clamp meter is an electrical test tool that combines a basic digital multimeter with a current sensor.

A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.

The Thermal Scan Monitoring System is an infrared imaging system designed to carry out the thermal imaging of the contact wire.

Insulation testers use a high voltage, low current DC charge to measure the resistance within wires and motor windings..
