美高尔MWA3xx变压器迷你分析仪说明书
DESCRIPTIONThe Megger MWA3xx Transformer Winding Analyzer is anadvanced 3-phase transformer test system delivering portability, reduced set-up time, increased job-site safety, and effortless productivity. The MWA3xx provides complete ratio, phase and winding resistance measurements for a 3-phase transformer. All ratio and winding resistance tests are performed in one instrument, with only one 3-phase lead-set connection. The MWA3xx utilizes PowerDB as a single software platform saving the user additional time with only one set-up and one easy-to-use test form.The MWA3xx effectively tests:n Power transformers n Distribution transformers nCTs and VTs (PTs)n Motors/generatorsTESTING PERFORMEDThe following tests are easily performed with the MWA3xx, all with one instrument and one 3-phase lead-set connection.n 3-phase turns ratio n 3-phase winding resistancen OLTC/continuity (make-before-break) n 3 phase core demagnetization n Magnetic balance / flux distribution n Excitation currentn Polarity and phase angle deviation n Auto vector detection nHeat-run test3-Phase test connection (no interconnect boxes)3-Phase, 2-Winding Transformers - Resistance on all six windingsOnce connected, the MWA3xx performs DC resistance measurements on all high- and low-side windings withoutreconnection. The test procedure is simple and efficient. Delivering eight-terminal/six-winding resistance measurement capabilitywithout the need for inter-connect boxes saves the user time by testing all six windings without having to disconnect and reconnect leads. The far-end of the measurement cable set is connected to each bushing/terminal of the transformer using a patented adjustable (100 mm – 4 in. opening) Kelvin clamp. This adjustable clamp removes the need for traditional dual leads (I & P) per phase, reducing the connections from 16 to 8 without the worry ofmisconnecting potential (P) for test current (I). The near-end of the cable is connected to the MWA3xx.

The test sequence can be selected as 6-winding with dual injection simultaneous winding magnetization, up to 4-winding measurement of HV and LV separately, or single-winding test.3-Phase turns ratioComplexity in the measured ratio versus nameplate ratio occurs with most three-phase power transformers due to multipliers, such as √3, which are required to match the measured ratio to the nameplate ratio. Additionally, transformers with zig-zag windings are handled correctly with internal compensation allowing usersto compare nameplate to actual with no corrections needed. The MWA3xx automatically applies the appropriate multiplier which provides a direct comparison to the nameplate ratio.Excitation currentThe excitation current test at low voltage is very useful in locating problems such as defects in magnetic core balance, in magnetic core structure, shifting of windings, failures in the turn-to-turn insulation, or problems in tap changers.Winding balanceWinding balance (also referred to as magnetic balance) is performed to assess the health of the windings, core assembly condition, and flux distribution within the transformer. This test, performed safely and efficiently by the MWA3xx, is a measure of how well balanced (electrically) the transformer is versus nameplate specifications. Check with the factory to ensure your vector group is available with this feature.Phase angle deviationPhase angle deviation is the phase relationship between in-phase vectors of the high-side windings versus the low-side windings. The phase deviation denotes the quality of the core and the winding and should exhibit very low values (0.01 degrees) when the core and windings are functioning properly. Shorted turns, a deteriorated, or damaged core can cause significant changes in the phase deviation values.LTC (OLTC) continuityIn normal LTC operation, continuity between the internal LTC contacts is maintained throughout each complete transition (from one tap position to the next). To check for this continuity, the MWA3xx continually monitors the transition current for each tap position. Any slight discontinuities are detected and reported. Vector recognitionWhen the transformer nameplate data is unavailable, or to confirm compliance to specified nameplate configurations, the MWA3xx provides the capability for automatic vector group detection. PolarityThe MWA3xx quickly and efficiently checks for correct polarity between high and low side windings.Automated heat-run interval testingThe MWA3xx performs automated single or multi-core heat run testing. It uses the standard accepted methods, IEC60076-2-1993 & C57.12.90 2013, for this test, allowing users to perform factory testing automatically. Reports included within software also meets IEEE and IEC standard requirements but does allow manipulation to fit individual customer requirements.Auto core demagnetizationIn order to avoid problems related to core saturation, the MWA3xx comes standard with a core demagnetization function which safely demagnetizes the transformer core after DC testing.PowerDB™ SoftwarePowerDB software provides the unit with a common “user interface” to minimize operator training and provides a seamless interface to the computer application – PowerDB Lite.Two Interface OptionsExternally controlled – MWA300The MWA300 is a “black box” style package that is remote-controlled by PowerDB software running on an external PC (not provided).Built-in 305 mm (12 in.) touch-screen computer –MWA330AThe optional built-in touch-screen computer software provides an industrial, high visibility screen for use on any day – bright or cloudy – and works under the toughest environments. Providing the same test capabilities as the MWA300, the MWA330A comes equipped with an internal computer providing a 305 mm (12 in.) color display with touch-screen interface.FEATURES AND BENEFITSn “One-time” 3-phase connection tests all six windings for faster and safer testing.n No switchbox required, ensuring easier and safer operation.n Unique Kelvin clamps with patented adjustable jaws each open to 100 mm (4-in.) as well as banana plug input for connectionto terminal blocks – no need for special lead sets, and minimal operator error due to lead connections.n Industrial grade 305 mm (12 in.) bright-color touch-screen display available as an option.

Instruction Manual
Model 4000VOC
Read and keep this manual for reference purposes
Service: 230 Volt, 50/60 Hz.
RV-1-220
Thank you for purchasing an Amaircare® portable air filtration system. With proper care and maintenance, your Amaircare® system will provide many years of reliable service, improving the quality of your air.
Closing the cabinet 1. Re-place filter access lid and secure it with the three retaining clips. 2. Replace safety screw from filter access lid.
The Amaircare 4000VOC ChemFilter is designed to remove VOC’s generated by solvent ink-jet plotters. The 4000VOC is installed directly into the rear of a plotter and creates a negative pressure inside the plotter. The VOC’s that are created in the printing process are drawn into the 4000VOC’s 30 lb. granulated carbon filters which remove a significant amount of the V.O.C.’s. The ‘clean’ air is then vented out of the bottom of the 4000VOC.
