Lightweight High Current Micro-Ohmmeters

The RMO-200G series micro-ohmmeters are the standard for many USA power utilities, offering a lightweight design and 200A current capability. These devices use a TRUE DC power source to provide ripple-free outputs, preventing false trips of breaker CT controls. The new RMO-H handheld high current micro-ohmmeter is ideal for use in bucket trucks and features a long-lasting Li-Po battery for all-day operation.

  • Standard Model: RMO-200G with 200A capability and lightweight design.
  • Handheld Model: RMO-H with a Li-Po battery for extended use.

CB Portable Power Supply: SAT40a 

The SAT40a combines the functionalities of the POB-40D with the accurate measurement of coil resistance, making it an ideal tool for optimal coil testing. CB coil failures are a common weakness in MV and HV circuit breakers.

  • Combined Functionality: Includes coil resistance measurement.
  • Reliability Testing: Addresses a common weakness in circuit breakers.


CB Coil Tester: POB40D 

DV Power’s POB40D CB Coil Tester is perfect for verifying adequate power supply to CB coils and spring charger motors, especially during commissioning when station DC is unavailable. It ensures coils operate at the lower end of their supply voltage rating.

  • Verification Tool: Ensures adequate power supply to CB coils.
  • Commissioning Aid: Useful when station DC is not available.
