Product Overview
TD4550 is a special for the verification of three-phase AC watt-hour meter, power meter portable instrument, its built-in three-phase standard source, with 0.02/0.05/0.1 level of three specifications optional. The basic electric energy error detection, watt-hour meter constant test, standard deviation, starting test, latent test and so on can be completed by using one equipment. Reference criteria: GB/T 11150-2001、JJG 597-2005、JJG 307-2006、JJG 596-2012, etc.
Functional Characteristics
At full load, the maximum output of the three-phase standard source V /120A,456 can guarantee the stability of the output value.
Current output minimum to 2 mA, is the basis for starting test of the tested energy meter.
Value adjustment has rotary encoder, bit adjustment, step ratio and other ways, can be three-phase adjustment or phase adjustment.
Phasor diagram shows: arbitrarily adjust the phase between three-phase electricity, and through the form of phasor diagram visual display.
Man-machine function: equipped with large-scale LCD touch color screen, visual value display, convenient operation.
Harmonic function (optional): can load 2~21 times, amplitude / phase adjustable harmonics, harmonic impact test.
Professional software (optional): support semi-automatic, automatic verification; data management, certificate export.
Main Application (0.05 level)
Calibration or verification of a three-phase active power watt-hour meter S 0.2 and below, a three-phase reactive power meter of 0.5 and below
Verification or calibration of a three-phase active power meter S 0.2 and below, a three-phase reactive power meter of 0.5 and below
Verification or calibration of three-phase AC voltmeters, ammeters, frequency meters, power factor meters, etc. of Class 0.2 and below
