Electrical Power Testing

1,250 products

Electrical power testing devices and supplies help ensure power systems and equipment operate reliably and safely, and reduce maintenance downtime. Digital multimeters measure voltage, current, and resistance in circuits, components, wall outlets, and other electrical devices and are ideal for field service work. Clamp meters measure the current draw in a live circuit to troubleshoot motors or other electrical equipment. Megohmmeters measure the electrical resistances of insulators such as cable jackets, electrical wires, and motor windings to determine current leakage and identify faulty or damaged insulation. Test leads connect electrical testing equipment to the device being tested to help provide safe and accurate test results. High voltage detectors and voltmeters are used to measure and monitor high voltage equipment to make sure current flow is at the correct levels.
