WOODWARD GOVERNOR COMPANY
PART NO: 8270-274
RAMP GENERATOR
MAKER REF. 8270274
ALTERNATOR 4200KVA 5500V.
ACCELERATE RATE: 0 TO 10 INC
LOW SPEED SETTING: 0 TO 10 INC
The Woodward 8270-274 is a ramp generator module produced by Woodward Governor Company, a globally recognised manufacturer of precision control systems for marine and industrial power applications. Functioning as a speed reference ramp control unit, this component governs the rate of acceleration and establishes low-speed thresholds within alternator and generator control circuits. It forms part of the broader Marine Control System architecture onboard, ensuring smooth, controlled power build-up during generator start sequences — a critical requirement for protecting both electrical machinery and connected loads in demanding shipboard environments.
Key Features
✓ Ramp generator function controls the rate of speed increase during alternator start-up, preventing abrupt load transitions and protecting downstream electrical equipment.
✓ Rated for alternator applications up to 4200 KVA at 5500V, with an adjustable accelerate rate and low speed setting, each configurable across a 0 to 10 increment range as specified in the original product data.
✓ Designed for integration within Woodward Governor Company control systems, compatible with governor and voltage regulator panels typical of marine generating sets — subject to confirmation against specific installation drawings.
✓ Suitable for installation within enclosed control panels or engine room automation cabinets; exact mounting configuration and environmental rating should be confirmed against the original system documentation.
✓ As a precision control module within a generator management system, correct replacement with the exact Woodward part reference is essential to maintain system calibration, response characteristics, and operational integrity.
Marine Applications
✓ Merchant vessels and bulk carriers utilising Woodward-governed main or auxiliary generating sets requiring controlled ramp-up during power station changeovers.
✓ Offshore support vessels and platform supply vessels where stable frequency and voltage build-up during generator synchronisation is operationally critical.
✓ Tankers and gas carriers with high-voltage distribution systems (around 5500V) demanding precise alternator speed control during start and load transfer sequences.
✓ Passenger vessels and RoRo ferries where uninterrupted power supply and smooth generator transitions are essential for safety and passenger comfort systems.
✓ Naval auxiliaries and research vessels equipped with Woodward-based automation and governor control systems requiring OEM-compatible ramp control components.
Why Marine Engineers Choose
Marine engineers specify the Woodward 8270-274 ramp generator for its OEM-precise control characteristics, ensuring that alternator acceleration profiles remain consistent with the original system design — minimising the risk of electrical stress, system faults, or governor instability during critical power management operations.
Ideal For
Merchant vessels, offshore units, tankers, passenger ferries, and any commercial or industrial vessel operating Woodward Governor Company control systems on medium- to high-voltage generating sets requiring reliable ramp control.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, testing and commissioning, component repair assessment, and retrofit or upgrade integration for Woodward governor and control systems. Compatibility with a specific installation is subject to confirmation — buyers are advised to share nameplate photographs, the full part number, any available system drawings or wiring diagrams, the governor or control panel model and software version, and vessel name or IMO number where relevant. Providing this information prior to ordering ensures the correct module is supplied and that any integration or configuration requirements are identified in advance.
