TE30 PC-Soft

The TE30 PC-Soft is a powerful software to expand capabilities of TE30 device of remotely connecting to device via USB, Bluetooth or Ethernet and enable use of a full array of testing and analysis. Software is dedicated for PC computers with Windows 2000/XP/Vista/7/8/10 and tablets with Windows 8.1/10.

The TE30 PC-Soft is used to remote control and monitor of the device and allows to:
• measuring and recording of all three phase power network parameters with digital, graph and oscilloscope display,
• verification of power network wiring with measure and recording of power network parameters by displaying of: three phase voltage and current vector, neutral voltage and current vector, direction of vector rotation,
• testing of electricity meters directly on site,
• testing of LV and MV current CT and potential PT transformers simultaneously in three phases directly on site,
• measuring of power quality parameters according to IEC 61000-4-30,
• store, export to MS Excel, copy to system clipboard and print the result of measurements and tests.

1. What will be the 1mA current measurement accuracy of direct current inputs?

The accuracy of the TE30 (class 0.05%) is defined as 0.05% of measurement value in range 10mA…12A and 0.05% of lower range (10mA) for values below 10mA.

It gives: 0.05%*10mA=0.005mA. For 1mA the relative error is: (0.005mA/1mA)*100%=0.5%. So the 1mA is measured with 0.5% of accuracy for TE30 class 0.05%.

2. I often test energy meters on very distorted power network. It is possible to find the source of the distortions?

Yes, it is easy by the unique function of power (P,Q) harmonic measurements.
The sign at the bars of power in spectrum diagram shows source of the distortion.
For the active power harmonics (P): if plus (+) then distortion goes from network to load; if minus (-) then distortion goes from load to network.

See the pictures below. Oscilloscope shows that U and I are highly distorted but only harmonics of power P with many long minus bars means that distortion goes from this customer to power network.

3. Can I use TE30 to test the ratio of MV (15kV) current transformer?

Yes, you can use special High Voltage current clamps up to 2000A at 40kV called AmpLiteWire, connected to the primary side of CT. The secondary side of CT can be connected directly to the TE30 current inputs or by precision 100A clamps to avoid breaking of the secondary current circuit. As the result you will get the ratio and phase shift error of the MV CT.

4. Error test of three-phase energy meter goes 33%. What is wrong?

Approximately 33% or 66% meter error test result means that there is a wiring problem.
At first make sure that TE30 voltage and current inputs are connected correctly to network/meter. Then use a Vector Graph measurements to find the problem. Probably one phase in your meter is disconnected/shorted or rotated.
Typical Vector Diagram shows picture below.

5. What should be done to use the REC functionality (network parameters recording) of the TE30 tester?

To use the REC functionality, user need to purchase a license key that extends the TE30 functionality with the REC function, enabling the measurement, registration and analysis of power quality parameters. The license key generated remotely by the manufacturer and can be uploaded by the user at any time after purchasing the device or by manufacturer when purchasing the TE30. Recorded parameters can be selected individually or automatically in accordance with the requirements of EN 50160.

6. What are the main differences between the TE30 and the TE30 Lite?

The TE30 Portable Three-Phase Workiing Standard and Power Quality Analyzer is manufactured in the 0.1% or 0.05% class, while TE30 Lite Portable Three-Phase Working Standard and Power Quality Analyzer is available in the 0.2% class.

The TE30 Portable Three-Phase Working Standard and Power Quality Analyzer enables direct current measurement up to 12A, while TE30 Lite enables current measurement up to 3000A with clamps only (depending on the selected optional measuring clamps).

LabView driver

Terminal communication

RS232, USB/RS232 or Bluetooth/RS232 communication with text command enable the easiest way to control all functions of the C300B in any system. If you want to use C300B calibrator in your own test system it will be fast and easy – just use the terminal.

To set 3-phase basic setting like voltage, current, angle and frequency, send commands:

1. What is the C300B Calibrator accuracy when temperature is over specified +20…+26°C temperature?

The specified temperature +20…+26°C range means, that in this range the accuracy of the C300B Calibrator is 0.02%. The influence of the temperature is included in this accuracy for this range of temperature.

For the temperatures below +20°C and over +26°C the additional temperature error is defined as: 0.1 of basic accuracy per 1°C, in temperature range +5…+20°C and +26…+40°C. This means, that the additional temperature error is: 0.02% * 0.1 = 0.002% per degree out of the basic temperature range.

Example: Assume that temperature of environment is 30°C and C300B Calibrator 0.02% basic accuracy. We will get: 30°C – 26°C = 4°C; 4 * 0.002% = 0.008% – this is additional temperature error. The total error for this 30°C temperature will be: 0.02% (basic error) + 0.008% (influence of temperature) = 0.028%.

In the same way for basic C300B accuracy 0.05% you will get: 4°C * 0.005% = 0.02% and then: 0.05% + 0.02% = 0.07%.

2. How to calculate the C300B current uncertainty? Does the Range in formula mean Full scale or Setting value?

The output current of the C300B Calibrator can be set from 0.001000A to 120.000A. The current is generated on 4 ranges: 0.5A, 6A, 20A, 120A. The guaranteed uncertainty of 0.02% of set value of current is from 10% of range (for example: 10%*0.5A=0.05A) 0.05A to 120A. Below 0.05A the uncertainty is 10% * 0.02% of range value (10%*0.02% * 0.5A = 0.00001A).

Examples:
• 5A* 0.02% = 0.001A (value of uncertainty in A) – because the 5A>0.05A, it is 0.02% of set value;
• 0.1A * 0.02% = 0.00002A – because the 0.1A > 0.05A, it is 0.02% of set value;
• 0.01A the uncertainty is 0.00001A (10%*0.02% of 0.5A range) – because 0.01A<0.05A so the relative error will be: (0.00001A/0.01A)*100% = 0.1% for setting 0.01A;

Conclusion:
From 0.05A to 120A the uncertainty is 0.02% of set value of current; for every current settings below 0.05A, the uncertainty is 0.00001A (10%*0.02% of the lowest current range 0.5A).

3. How to increase calibrator output current to 360A and 3000A?

C300B Power Calibrator has an isolated current outputs so when you set the same angles between them it is possible to put together 3x120A currents to 1x360A. It’s easy with the EA30 cables and terminals.

When you want to test CT clamps you can use the coils. For example with ZW100/10A up to 3x1000A and up to 1x3000A when three phases are summed.

4. How to generate the rectangular waveform?

It is possible to generate the rectangular signal on C300B outputs using Harmonics function and Fourier representation of the rectangular waveform.

General formula to calculate the value of harmonic amplitude in [%] is: 100/Number of harmonic. Example of amplitude calculation for 3rd harmonic: 100/3 = 33.33%. Picture with waveform captured from Calpro300 Software is presented below.

5. What should be done to use the Calpro 300 TS and Calpro 300 PQ functionalities using C300B Calibrator?

To use the Calpro 300 PQ functionality, user need to purchase a license key that extends the C300B functionality with the Calpro 300 TS or Calpro 300 PQ functionality (or both).

The Calpro 300 TS functionality makes it possible automated or manual testing of: electricity meters, current clamps, current transformers, measurement transducers, protection relays (for Trigger Time and Trigger Level).

The Calpro 300 PQ functionality makes it possible generating sinusoidal and nonsinusoidal voltage and current, which value is changed in time for testing meters, recorders and power quality.
