Get on-line with Beckwith Electric’s Syncrocloser products: sync-check, automatic synchronizing and speed/voltage matching relays. They offer the best accuracy in the industry to assure safety for your most expensive asset.

Your Benefits:

Ability to get on-line quickly—
- Unique proportional-pulse width-to-setpoint error algorithm takes into account the inertia lags in rotating machinery and control lags found in governor controls
- Commissioning is made easy with large calibrated control knobs for all tunable parameters. (No need to scroll through menus while the system is being tuned)
- Assure desirable power flows with the ability to select synchronize with VAr export and real power export on synchronizing

Enhanced security and operational use—
- Best accuracy in the industry - Ability to use “operator window” to supervise operator closure of generator breakers - Ability to use phase angle/slip frequency (versus phase angle/time) synch-check so close tolerance phase angle settings can be maintained - Phase angle/slip synch check can be used in generator or bus tie applications - Rack-mount and retrofit-style cases, including vertical mount

Generator Synchronizing
Smooth, efficient and safe synchronizing of generators, transfer of plant auxiliary motor buses or reclosing of transmission line breakers are the ultimate reasons for using equipment in the Syncrocloser Line. Each of the products has been carefully engineered to virtually eliminate the possibility of damage caused by faulty synchronizing.

Safeguard the Source! The M-0193 Syncrocloser (Automatic Synchronizer) exhibits the best accuracy in the industry for advance closing angle prediction to lead to close at 0° phase angle difference. If you don’t think accuracy is important, did you know that a 12° phase angle difference can hard-load a machine with 30% of full-load shock? That is stress your machines should not endure! This is especially true for peaking machines that are synchronized daily, and large base-load machines that are built with tight tolerances.

Application Flexibility–The M-0193 Automatic Synchronizer can be multiplexed to different generators that have different breaker closing times. An infinite amount of different breaker closing times can be obtained by simple contact closures to the M-0193 relay.

Ease-of-Use–In a world of menu-driven HMIs on relays, the M-0194 Speed and Voltage Matching Relay has simple and simultaneous access for all tunable parameters. The ability to have all parameters with easy-to-read, clearly-marked controls is a great asset to get the commissioning task performed properly and in a timely fashion.

Scalable Application–Based upon the importance of the generation asset, relays may be applied in series for greater security; synch-check relays can be used to back up an autosynchronizer or operator. Speed and voltage matching relays may be used with autosynchronizers for completely automated synchronizing sequences. Synch-check relays may also back up control systems with integrated synchronizing for improved security, and to provide a supervised manual synchronizing path.

Concise Speed Control–Using a unique proportional-pulse width-to-setpoint error algorithm, the M-0194 Speed and Voltage Matching Relay is able to cope with the inertial lags in rotating machinery and control lags found in governor systems. These lags, if not properly compensated for, cause the speed (frequency) of the machine undergoing the synchronization process to hunt excessively— resulting in long synchronization times, wasted fuel and possibly a generator trip on incomplete sequence timing. For peaking service, the proportional pulse width-to-setpoint error algorithm offers the fastest synchronizing times.
