Portable Three-Phase Working Standard and Power Quality Analyzer
Electricity meters tester class 0.05% and 0.1%. Three phase tester of current transformers and analyser of power network quality. It makes possible electricity meters testing on the site or in the laboratory.
TE30 Portable Three-Phase Working Standard uses large 7 inch LCD display with touch panel for setting and presenting measurements. TE30 is able to save measurement data on SD card, save a BMP screen capture and print measurement report directly to Bluetooth printer. Analyzer can be also connected by USB, Bluetooth or LAN with PC computer or Tablet and setting by TE30 PC Soft.
TE30 is an universal device and can be used as a:
- Three-Phase Power Network Analyzer
- Energy Meter Tester
- Instrument Transformer Tester
- Power Quality Analyzer IEC 61000-4-30
Three-Phase Power Network Analyzer
TE30 Analyzer 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. |
Energy Meter Tester
TE30 Tester offers automatic and easy to use function for energy meter testing. TE30 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. |

Instrument Transformer Tester
TE30 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. |
Power Quality Analyzer IEC 61000-4-30 (REC function)
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. |
