PORTABLE THREE-PHASE METER SITE ANALYZER

RW-30X
RW-31X

The RW-30X and RW-31X are high-accuracy field meter site analyzers designed to verify the performance of installed electric meters, CTs, and PTs under real-world operating conditions.

Engineered for utility field crews and technical specialists, the RW-30X and RW-31X enable precise measurement, analysis, and validation of single-phase and polyphase transformer rated metering installations without removing the meter from service. Their stable measurement platform allows users to quickly identify metering errors, wiring issues, and installation problems with confidence.

Product Highlights

RADIAN RW-30 and RW-31X Meter Site Analyzers deliver comprehensive three-phase field testing and site analysis utilizing the Radian Research RX reference standard as its measurement engine. With its fully automated design, it significantly reduces testing time while ensuring unparalleled precision and compliance with industry standards.

The RW can perform a complete meter site analysis encompassing power quality, meter testing, and transformer testing without removing the meter. Capabilities including Waveform Capture, Harmonic Analysis, CT Testing, Vector Diagrams and Trend Recording provide validation and peace of mind that the entire metering installation is correct.

The intuitive touchscreen interface of Winboard Embedded Testing Software leads you step by step through installation, wiring checks, testing, and record keeping. Unlimited test profiles, sequences, and site configurations may be created and saved.

Test results are stored and fully compatible with industry leading WECO WATT-Net™ Meter Test Data and Asset Management software platform, for ultimate enterprise level management of your field testing operation. Data can also be exported as simple Microsoft Excel, user-defined, or PDF files.

RW-30X & RW-31X Options

RW-30X

The RW-30X consists of an integrated true three-phase voltage and current source with a RADIAN RX-30 Three-Phase Reference Standard as its measurement engine. The RX-30 has a guaranteed accuracy of ±0.04% for all of its measurement functions. The RW-30X supports meter testing using controlled voltage and current sources as well as customer’s load.

RW-31X

The RW-31X consists of an integrated true three-phase voltage and current source with a RADIAN RX-31 Three-Phase Reference Standard as its measurement engine. The RX-31 has a guaranteed accuracy of ±0.02% for all of its measurement functions making it ideal for testing of highest accuracy class meters. Like RW-30X, the RW-31X supports meter testing using controlled voltage and current sources as well as customer’s load.

RW-30X/RW-31X NS

The RW-30X NS and RW-31X NS (No Source) allows you to test a meter using customer’s load and service voltage. Two accuracy options are available through selection of the desired RADIAN RX Reference Standards: ±0.04% (RW-30X NS) and ±0.02% (RW-31X NS).
