A battery-powered digital micro-ohmmeter, LRTS10, is designed by Vacuum Interrupters for low-resistance testing of electrical connections. It is designed for applications including switchgear, circuit breakers, busbars, transformers, motors, cable terminations, and grounding connections. Working on all Milwaukee M18 batteries, the unit offers six selectable test currents with resolution down to 1.0 µΩ.

The US based leading developer and manufacturer of electrical testing equipment, Vacuum Interrupters, has introduced the LRTS10, a battery-powered low-resistance test set designed to make electrical connection testing easier in the field, workshop, and laboratory for medium-voltage vacuum circuit breakers and contactors.
The LRTS10 is a digital micro-ohmmeter that operates on Milwaukee M18 REDLITHIUM batteries. This gives technicians a practical option when working at sites where access to a power source may be limited. Instead of waiting for the test equipment to recharge, users can replace the battery with a charged pack and continue testing. The unit is compatible with all Milwaukee M18 batteries.
The company supplies the LRTS10 with test leads, a cable bag, a charger, and an M18 XC5.0 battery. According to the company, the supplied battery can support more than 1,100 tests.
The instrument provides six selectable test currents and measures resistance with a resolution of 1.0 µΩ. On the 10 A range, it offers a measurement accuracy of 0.2% + 5.0 µΩ. Technicians can check low-resistance electrical connections and can identify issues during inspection and maintenance.
The new LRTS10 is intended for a range of electrical equipment and connections. Its applications include switchgear, circuit breakers, bolted busbar joints, cable terminations, lugs, transformers, and motors. It can also be used to check grounding and bonding connections.
Electrical connections are intended to have minimal resistance. So, the new low-resistance testing kit confirms the resistance. Poor or deteriorated connections can affect equipment performance and may lead to unwanted heating or other electrical problems. A portable test instrument can therefore help maintenance teams perform these checks without relocating equipment to a dedicated testing facility.
With the LRTS10, Vacuum Interrupters combines low-resistance measurement with a rechargeable battery platform already used by many electrical and maintenance crews. Its portable design is aimed at technicians who need to carry out repeated resistance tests across different work locations.
