Doble F6150 Power System Simulator 3-Phase Relay Test Set

Doble F6150 Power System Simulator 3-Phase Relay Test Set

The Doble F6150 Power System Simulator is a high-power secondary injection instrument engineered for comprehensive commissioning, diagnostic evaluation, and periodic maintenance of electrical power system protection schemes. Featuring twelve independently controlled AC/DC signal sources (six convertible voltage/current channels and six dedicated high-compliance current channels), the F6150 handles demanding high-burden electromechanical induction disk relays, solid-state devices, and advanced digital multi-function numerical relays.

Designed to bridge benchtop precision with rigorous field survivability across utility substations, offshore marine platforms, and generation facilities, the unit executes steady-state calibration, dynamic fault state sequencing, and transient waveform playback (COMTRADE) without external signal boosters. This specific unit is offered in Surplus / Pre-Owned (Power Tested As-Is) condition.

Frequently Asked Questions

Can the Doble F6150 test high-burden electromechanical relays without tripping internal amplifiers?

Yes. The F6150 delivers high compliance voltage per channel, enabling it to drive continuous current through high-impedance coils found in older electromechanical overcurrent relays such as the Westinghouse CO and GE IAC series without dropping out or clipping.

What is the maximum current output achievable with this unit?

In standard 6-phase operation, each channel delivers up to 17.5 A continuous. By configuring channels in parallel using manufacturer bridging bars, the system delivers single-phase outputs exceeding 100 A continuous, with short-duration transient bursts up to 180 A.

Does this unit include the Doble Protection Suite software license?

This surplus hardware is supplied as a standalone test set (power tested as-is). End-user software licenses, such as Doble Protection Suite or F6Test, must be obtained directly through Doble Engineering or matched with your organization’s existing enterprise dongles.

How does the convertible source architecture work?

The F6150 includes 6 convertible sources capable of operating either as standard AC/DC voltage sources (up to 300 V RMS) or as low-range, high-power current sources. This permits configurations like 6 voltages + 6 currents, 3 voltages + 9 currents, or parallel high-power modes.

What is verified under the “Power Tested As-Is” condition?

The unit has undergone cold-boot power verification confirming internal motherboard bootup, fan spin, DC supply rail integrity, and diagnostic LED status. Secondary injection calibration against precision reference standards and exhaustive channel load verification have not been performed.
