SMG8000 Three-phase Power Meter Calibrator, it is specifically designed for on-site inspecting the running error and fault of power meter in electric system. The instrument is due to sampling with high-precision internal transformer and clamp-type transformers, so that allows the operator to quickly, safely and reliably measure the error and wiring fault of power meter, which provides effective basis for operator to
Overview
Functions and features:
3.1 Adopt TI 32-bit high-speed 150MHz DSP and the AD company's high-performance 12-channel and 16-bit AD the use of floating-point operation to ensure the accuracy of the calculation.
3.2 The instrument uses a large 10.4-inch industrial grade TFT color screen the interface display is clear beautiful and informative every parameter of function will be displayed in the screen is a screen display of all parameters which make the user clear when in operation.
3.3 Can measure active energy error reactive power error voltage current active power reactive power phase frequency power factor display the vector and check out results.
3.4 Can simultaneous measure active reactive and the error between the two energy meters: with high efficiency which is two time of the traditional calibrated method.
3.5 Wiring simulation function: When the instrument not access voltage and current signals can be simulated in a variety of wiring the office site and then get a appropriate wiring result. Can be as a training tool to improve the staff skills to check line.
3.6 Unbalance measurement: can measure the voltage quality for three-phase three-wire three-phase four-wire current unbalance can detect hidden faults stealing electricity leakage and other anomalies fast and simple.
3.7 5A clamp error self-checking: the instrument can produce 5A 0.5A current signal to the 5A current clamp to measure the clamp meter error. Can calibrate the 5A clamp after a long-time operation.
3.8 PT CT secondary load on-line test.
3.9 Energy accumulation function can check if there is any energy pulse output meter or to test energy-saving target.
3.10 Measuring three-phase voltage and current waveforms and three-phase voltage and current harmonics 2-21 to keep abreast of quality of power supply.
3.11 In high voltage power supply the un-load wiring also can identify the 2mA current at minimum.
3.12 With 5A 100A 500A 1000A Clamp can measure the low-voltage current transformer turns ratio directly. Can identify the CT secondary circuit breaker poor contact turn-to-turn short circuit whether the CT nameplate ratio is same as actual CT ratio.
3.13 Without adjustable resistance in instrument all correction by the the software.
3.14 With Chinese input the input keyboard is same as computer keyboard layout arrangement applicable for spelling wubi and stroke and other Chinese input methods.
3.15 The electronic instrument is build-in 1G memory can download 5000 user’s data the parameters and downloaded data from all site that may need to enter freely defined by the user.
3.16 Has a USB interface USB connection form a large space easy to copy data.
3.17 Optional for barcode scanner can automatic entry meter coding.
3.18 Optional for 485 or infrared radio head readout multi-function meter peak flat valley all the numbers of active skills. Support for GB DL645 Langille IEC1107 statute.
3.19 Can automatic readout multifunction power meter data.
3.20 Scalable PT secondary voltage drop test functioncan automatic detect the integrated error which cause by voltage transformer secondary voltage dropping.
3.21 Scalable wireless audit function by auditing the host can gather module without wiring combine with 0-3 sets extension can comprehensive detect fault spot metering system inspect integrated high-voltage and low-voltage error.
3.22 Measurement without blind zone can measure all kinds of domestic energy meter.
