https://www.mktester.com/transformer-test-system/transformer-comprehensive-analyzer/transformer-calibrator.htmlProduct description#65306;

Transformer calibrator is a new automatic instrument. We apply advanced electronic technology in the design. By directly decomposing the error signal, it is able to display the percentage, phase error and orthogonal error statistically. Its quick and energy saving. And its especially good for live testing due to its cute dimension and light weight.



Technical Parameters#65306;

Working Condition:

(1) Temperature: 5#8451;-40#8451;

(2) Relative humidity:<80%(25#8451;)

Altitude: <2500m

Power Frequency: 50Hz0.5Hz

Power Voltage: 220V5V

(2)Measuring Range:

In-phase component(%):0.0001~200.0 Resolution: 0.0001

Orthogonal Component (min):0.001~ 700.0 Resolution: 0.001

Impedance(#937;):0.0001~20.0 Resolution:0.0001

Admittance(ms):0.0001~20.0 Resolution:0.0001

(3)Basic Error:

In-phase Component: #916;X=(X2%+Y2%)Dx (with Class 1 to spare)

Orthogonal Component (with Class 1 to spare)

X#12289;YValues Displayed

Dx, DyQuantified Error Dx=2, Dy=5

(4)Percentage: Class 2 (with Class 1 to spare)

2.2 Working Range:

(1) Current:#65288;1%#65293;149%#65289;In #65288;In =5A#65289;

#65288;5%#65293;149%#65289;In #65288;In =1A#65289;

(2) Voltage:#65288;5%#65293;149%#65289;Un #65288;Un =100V#65292;150V#65292;100V/ #65289;

#65288;5%#65293;200%#65289;Un #65288;Un =100V/3#65289;

2.3 Work Load:

(1) Current: TO to TX#65308;0.12#937; cos#934;=1.0

(2) Voltage: a to x#65308;0.25VA #65288;100V#65289;



Functional Features

1. Detect the phase error, ratio error of CT and PT.

2. Test the impedance of secondary load of CT.

3. Test the admittance of secondary load of PT.

4. Measure small AC current and small AC voltage.

5. Bearing RS232 interface.
