TE30 Lite is our newest universal 4-in-1 device combining functions of:
TE30 Lite Tester is a continuation of TE30 Lite (Three-Phase Power Network Analyzer and Tester of Electricity Meters and Instrument Transformers.
In one case, TE30 can offer all you need and more:
Read the Data sheet and the rest of the website to know all functions of the TE30 Lite Tester. You will find there information about:
TE30 Lite Tester is used to measure and refresh all power network parameters in real time. Data can be displayed in four different ways: table, vectors diagram, oscilloscope diagram and harmonics in bar and table format.
|Table Display function is used for indicating all relevant parameters of three phase power network. The actual value of parameter helps to analyse circuit condition like: voltage missing, current missing, current reversal, asymmetry, etc.|
|Vectors Display function is used for verification of power network wiring and meter connection. Three orientation of vectors can be chosen.
Additionally the voltage unbalance (voltage asymmetry), phase sequence, neutral voltage and neutral current is calculated.
|Oscilloscope Display function is used for displaying the waveform of voltage and current change in time. Six parameters and 1, 2 or 4 periods can be displayed at the same time (picture presents an example waveform of 1-phase Switching Power Supply input voltage and current).|
|Harmonic Measurement function is used for measuring amplitude and phase of harmonic in voltage, current, active power and reactive power up to 63rd harmonic. The measured harmonic can be displayed in tabular and bar format. Total harmonic distortion THD, total distortion factor TDF, crest factor CF, total interharmonic distortion TID will be displayed as additional information about a form of analysed voltage and current.|
TE30 Lite Tester offers automatic and easy to use function for energy meter testing. TE30 Lite can be used to test error, test register and Pmax test directly on site with used load. All functions can measure energy for active, reactive and apparent power P, P+, P-, Q, Q+, Q-, S and energy for the first harmonic of active and reactive power PH1, PH1+, PH1-, QH1, QH1+, QH1-.
|Meter error calculating (partial errors, average error, standard deviation) directly in [%] with:
– method of settings time of measurements or number of impulses,
– automatic identification meter constant,
– automatic determining measurement time or number of pulses.
|Register testing for calculating of register error directly in percentage. Three registers can be verified at the same time and any combination of measured power can be chosen.|
|Maximum power measuring for testing of maximum power (demand) meters.|
|Measurement data can be visualized in form of trend chart or table and are easy to save, read in the future and print.|
TE30 Lite Tester can be used for automatic testing instrument transformers like LV and MV current CT and potential PT (VT) directly on site.
|Burden Test function is used for calculating of current transformer CT and potential transformer PT burden directly in percentage (Percent Nominal Load) simultaneously in three phases.
Calculating of phase shift of load is enabled.
For easiest measurements, data from calculation of wiring and fuse resistance can be included into burden error.
|CT Ratio Test function is used for calculating of current transformer CT ratio and phase shift error directly in percentage simultaneously in three phases.
PT Ratio Test function is used for calculating of potential transformer PT ratio and phase shift error directly in percentage simultaneously in three phases.
For easy real time measurements of power quality a standard function Power Network Analyzer can be useful.
Additionally special function Trend Chart Display can easy visualize of measurement result in real time mode.
|Trend Chart Display function is used for displaying the changes in time of all relevant parameters of three phase power network.
Analyser can store all parameters averaged in 1-100 seconds step time.
User can display simultaneously up to 3 trend charts of any stored parameters.
|For advanced and long term analyse of power quality TE30 offers a Recording function.
Recording function is used for registration of all network parameters and additionally for measure dips, swells, interruptions, interharmonics, signal voltages and flicker.
Data with time stamp are stored in the SD card (up to 32GB) for archive and further analyse in TE30 PC-Soft program. It is able to check for EN 50160 compatibility or for individual users requirements.
