PowerMaster® Model 8833 Transformer Rated Metering Site Training Bench

The PowerMaster® 8813 is a true 3-phase training simulator for metering technicians to help improve their troubleshooting skills for applications encountered in the field. The Model 8813 provides a safe, controlled environment to help the trainee accelerate their education in meter testing and wiring verification. The training simulator also features the ability to simulate over 130 commonly found metering errors in the field. Paired with the Training Administrator Station (TAS), the bench can be controlled remotely over a closed WIFI network, and each trainee’s performance is recorded and time stamped for every session.

Troubleshoot Metering Connections

The PowerMaster® 8833 Transformer Rated Training Bench allows the technician to test meters under customer load (passive) or provide an artificial load (active) from the PowerMaster test equipment. The Trainer can simulate field conditions by adjusting amplitudes and phase angles to test the electric meter under a variety of conditions, including conditions beyond its calibrated range. Using a variety of Error Scenarios, Trainees can safely learn about metering problems they may encounter in the field for a customer complaint call.

Troubleshoot Instrument Transformers & Wiring

The Model 8833 allows the technician to test both CTs and PTs installed on the training simulator using a PowerMaster analyzer. The configuration allows easy access for flexible current probes, clamp-on probes, or Amp/Volt Litewire probes. By simulating different amplitudes from the Model 8833, the technician can learn how instrument transformers perform outside of their rated accuracy range.

Simulate Errors Found in the Field

One of the most powerful features of the Model 8833 is the ability to simulate more than 130 metering errors commonly found in the field within the comforts and safety of a lab environment. The PowerMaster® 8833 is designed to automate pre-defined error scenarios that do not require the user to physically change or modify any wiring. The Trainer can also override amplitudes and phase angles for further troubleshooting and run simulations of prior errors encountered in the field.


The PowerMaster® 8833 takes every consideration to ensure the classroom maintains a safe environment for teaching. The Model 8833 has a resettable Ground Fault Interrupt (GFI) for each energized point with a 5mA trip point and <200ms trip response. The PowerMaster® 8833 also includes a lighted beacon mounted on top to alert when the bench is active, and each meter, CT, and PT have illuminated lights when energized. Before a test can begin, the Trainee must interact with the bench to ensure all PPE is properly outfitted. The Model 8833 Transformer Rated Training Bench has a manual Emergency Stop integrated both on the bench and located on the touchscreen display. In addition, the Training Administrator Station (TAS) can remotely E-Stop a single bench or all connected benches simultaneously.
