5.Characteristics

☆Wide range output capability

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

The wide range of output capabilities can meet the calibration requirements of mainstream single/three-phase zinc oxide lightning arrester testers.


☆High Stability Output

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

The standard source output of TD1170 is characterized by high stability. It adopts the design principle of a closed-loop negative feedback system, which can measure and adjust the output power value in real time, ensuring the real-time stability of the output and enabling high repeatability measurements for a long time. Its AC voltage/current output has a typical stability of up to 0.01%/min.


☆ Full Current Vector Synthesis

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

TD1170 can separately set the resistive fundamental current (IPR1), the resistive third harmonic current (IPR3), the capacitive fundamental current (IPC1) and the vector synthesized full current, and its phase and amplitude are programmable and adjustable.

Full current output vector synthesis formula: I=IPR1 sinωt + IPR3sin(3ωt +π) + IPC1 sin(ωt +π/2)


☆Power Test

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

TD1170 adopts side panel wiring method to independently output AC voltage and AC current.

The three-phase voltage and current are independently output and the phase is adjustable to form a virtual power standard source, which is used to detect the power indication error of the tester.


☆Multiple Value Output Methods

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

Fixed-point output: Directly set the required output value through the digital buttons on the front panel or click on the touch screen, and the instrument will automatically switch to the best range output.

Especially when setting the power, just input the voltage value, current value and frequency directly.

When setting three-phase power, it supports three-phase unified adjustment or separate phase adjustment.

Rotary knob: The value output can be increased or decreased by rotating clockwise or counterclockwise.


☆Multiple Value Output Methods

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

When calibrating the instrument under test, it is usually necessary to select calibration points according to the proportion of each range of the instrument under test.

Users can easily select the calibration point of the meter under inspection through the "percentage output button" on the panel of the instrument or the "percentage calibration point" on the touch screen.


☆Harmonic loading function

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

S/N

Function

Sets the amplitude of the selected harmonic, either as an absolute value of the voltage or current harmonic, or as a percentage of the fundamental.

Sets the phase of the selected harmonic (relative to the fundamental).

The instrument has the output function of the 2nd to 21st harmonics. The embedded software is equipped with a user-defined "harmonic parameter setting" interface. The user can set the required harmonics according to the test requirements.

It has an oscilloscope function to observe the AC power waveforms of each phase after loading harmonics.

The spectrum of each harmonic is visually displayed in the form of a histogram (the fundamental wave is 100%).


☆Analysis Function

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

S/N

Function

Displays the amplitude and phase of each phase voltage/current (based on UA).

Click CH for menu, and the user can choose the power level to be displayed or hidden.

The phasor diagram displays the voltage and current of each phase.

Multiple electric parameter display:

UA, UB, Uc: A / B / C phase voltage;

IA, IB, Ic: A / B / C phase current

∠UIA, ∠UIB, ∠UIB: phase angle between A/B/C phase voltage and current;

IRA, IRB, IRc: resistive current of A/B/C phase;

Max: maximum value, Min: minimum value, P-P: maximum value-minimum value,

Avg: average, S.dev: standard deviation

S.dev/Avg: The ratio of the standard deviation to the average is the stability. ppm or % display can be switched.


☆Calculating Function

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

S/N

Function

Multiple electric parameter display:

UA, UB, Uc: A / B / C phase voltage

IA, IB, Ic: A / B / C phase current

∠UIA, ∠UIB, ∠UIB: Phase angle between A/B/C phase voltage and current;

IRA, IRB, IRc: Resistive current of A/B/C phase

PA, PB, Pc: Power of phase A/B/C.

Switch to set the electric power proportional formula kx+b or N1/N2 ratio.

Click on a certain value in the "Multiple electric parameter display" area to enlarge the calculated value and display it.

E.g. f(UA) is UA multiplied by the proportion value.


☆ Test Software

TD1170 Zinc Oxide Lightning Arrester Tester Calibration Device tunkia

Optional automated calibration software is suitable for various single/three-phase zinc oxide arrester testing instruments.

Supports fully automatic or semi-automatic calibration of the inspected equipment, raw data recording, analysis, management and customized template report export.

*(During fully automatic calibration, the equipment under inspection should have communication functions and open communication protocols to enable data reading.)

Software functions can be customized according to customer needs and software upgrades are supported.

The communication protocol and control command set are open, allowing users to develop their own control systems or set up automatic test systems.
