Product Description

TE*0 Three Phase Network Analyser and Tester of Electricity Meters and Instrument Transformers is used for:

- verification of power network wiring with measure and recording of power network parameters,

- calibration and testing of electricity meters and instrument transformers (CT Current Transformers and PT Potential Transformers) directly on site.

Large Touchscreen with display and keyboard functions for easy operation enables:

Measure of power network parameters:

- voltages U1, U2, U3, U*2, U*3, U*1, UN, 

- currents I1, I2, I3, IN, 

- frequency f, 

- phase angles j1, j2, j3, 

- power factors PF1, PF2, PF3, SPF, 

- factors sinj1, sinj2, sinj3, Ssinj, tgj1, tgj2, tgj3, Stgj, 

- angles between voltages U*2, U*3, U*1,

- powers P1, P2, P3, SP, Q1, Q2, Q3, SQ, S1, S2, S3, SS,

Visualization of measurement results in form of: 

- table, 

- vectors, 

- trend chart, 

- oscilloscope (waveform),

- or bar chart (harmonics of U, I, P, Q).

Testing of electricity meters directly on site:

- function of calculating meter error (partial errors, average error, standard deviation) directly in [%] with method of settings time of measurements or number of impulses,

- function of automatic identification meter constant,

- function of automatic determining measurement time or number of pulses,

- function of measuring energy with method of setting time for verification of meter counters directly in [%],

- function of maximum power measuring for testing of maximum power meters,

- visualization in form of table or trend chart,

- function of measuring energy for power P, P+, P-, Q, Q+, Q-, S,

- function of measuring energy for the first harmonic of active power PH1.

Testing of instrument transformers (LV and MV current CT and potential PT simultaneously in three phases) directly on site:

- functions of calculating transformer ratio error directly in [%],

- functions of calculating phase error,

- functions of burden measurements of transformer.

Power quality analyser function enables:

- measuring of power quality parameters according to IEC *********0 class A with visualization of measurement results in the real time mode,

- recording of power network parameters in the SD Flash ***2GB memory, which gives (8¸*4)x*06sets of network parameters or long-term registration of power quality,

- analyzing of measurement results for EN ****0 compatibility or individual requirements of user.
