Harmonic Generation

Thanks to the Model 4330’s harmonic generation capabilities, you can now put various meter brands and meter technologies through a full harmonic and trend analysis. With generation to the 60th harmonic and independent harmonic control in each of the current and voltage circuits (6 channels) as defined by order, magnitude and phase, you can get the full picture of how a metering device is going to perform.



We’ve extended the analysis functionality of the Model 4330 to bring real world field conditions back to the shop. Captured harmonic and/or trend data from the WE-30 can be played back allowing various meters to be tested under actual field load conditions. The load condition can be automatically played back from the captured data, providing multiple accuracies per meter “revolution” and the average accuracy of the entire test.



Multiple VAR and VA Test Types

There is more than one way to run a VAR or VA test, and ANSI is constantly approving new calculation methods. Unlike other test systems, the Model 4330 allows you to select from any ANSI approved calculation method to test a meter. This gives your utility the ability to choose the method that best fits its structure and needs, rather than having to accept the single method that a particular system is capable of testing.



Voltage and Current Circuit Burden Testing

Little things can add up when you’re talking about the thousands, or millions, of meters and attached modules that a utility might have out in the field. For instance, how much power does a particular brand of meter draw, or how much demand does running an AMR module pull? The Model 4330 can let you get those answers before a meter ever leaves the shop. During testing the Va burden is displayed as a metric.



Overview




The Model 4330 automated test platform is the touchstone in meter testing hardware. Building on our tradition of delivering testing solutions that provide a powerful mix of accuracy, convenience, and versatility, the Model 4330 adds next generation features and cutting-edge technology.



The foundations for this revolutionary test system are the features and innovations that have put WECO at the forefront of the industry for over thirty years. Low insertion force Smart Socket™ technology, fitted with high conduction gold connections, mechanically controls the insertion and removal of meters, providing an excellent connection and extended hardware lifespan. A laser based optics system employing high intensity light delivers highly accurate results from black marks or creep holes through even the dirtiest covers. Front mounted controls allow simple test selection and testboard control. An optional barcode scanner and printer cuts meter processing and data entry time. The optional OPTOCOM™ interface allows the meter to be tested and programmed without ever having to change the head.This foundation of innovative hardware is bolstered by WECO’s fully integrated Winboard3™, WATT-Net™, and WATT-Net Plus™ software.



With Winboard 3 you can build advanced test sequences that allow you to control every parameter of a test, simplifying even complex tasks, and generate results that are compatible with all major databases (MS SQL, Oracle, Sybase). The WATT-Net family of data management solutions gives you unparalleled test result organization, reporting, and exporting abilities. This combination of hardware and software allows you to utilize Turbo Test™ technology. Slash the amount of time it takes to test a supported meter to nearly one-fifth of regular testing time. The Model 4330 builds on these hallmark features with a robust set of innovations designed to help utilities maneuver today’s real world metering issues.

Fuseless Hardware Protection

With this latest generation of test system we aimed to build the most reliable hardware on the market. One of the innovations we’ve developed to keep downtime to a minimum is fuseless circuit board protection. Now you can spend more time testing and less time performing maintenance.

OPTOCOM™: With this optional interface you can test and program meters without changing heads. Just clamp the head on for testing and forget worrying about aligning optics or detecting creep holes. When the test is complete you can program the meter without replacing heads. The OPTOCOM™ option
takes the error and effort out of meter testing.


Turbo Test™: WECO has worked hand-in-hand with the industry’s leading meter manufacturers to bring you Turbo Test™ technology. Slash the amount of time it takes to test a supported meter on either WECO’s 2300 or 2350 three-phase testboards to nearly one-fifth of regular testing time. Convenient software wizards make setting up and running a Turbo Test as easy as it is fast. Save your shop valuable time and money with WECO’s Turbo Test option.
