in the EPR60 ?

General Information:
The EPR60 three phase rotation indicator (also called: non-contact phase detector) is a major breakthrough in the traditional phase sequence detection method. In the traditional phase sequence detection, the terminal of the three-phase wire must be removed, and the three exposed clips or test pins of the phase sequence meter must be connected to the exposed 3 live wires, and EPR60 adopts clamp-shaped non-contact inductive measurement. There is no need to remove the wires or touch the high-voltage exposed live wires. Directly clamp the three ultra-inductive high-insulation clamps to the insulation skins of the three-phase live wires to detect phases. At the same time, sound and light indicate the positive or negative state of the phase sequence of the three-phase power supply.

The EPR60 three phase rotation indicator also has functions such as live line inspection, simple power inspection, open circuit search, break point location, line maintenance and so on.

The EPR60 three phase rotation indicator is quick and convenient to detect, and the display is clear at a glance, which greatly improves the safety of on-site testing, effectively protects the personal safety of operators, and increases productivity. It is the three-phase power supply phase sequence, motor detection, and circuit maintenance. Safety equipment.
