Main features
This instrument has 12 detection functions and can test various single-phase transformers and three-phase transformers using different methods. The instrument adopts a large screen Chinese display with a micro printer, which is very convenient to use.

♦ Empty load test detection function:
Three phase four wire method no-load test
Three phase three wire method no-load test
The winding is connected to a single-phase no-load test with a delta connection
Winding connected to Y for single-phase no-load test
Single phase transformer no-load test

♦ Load test detection function:
Three phase four wire load test
Three phase three wire load test
Winding connected to single-phase load test with △ connection
Winding connected to single-phase load test with Y connection
Single phase transformer load test

♦ Capacity judgment and detection function:
Select internal power supply to determine capacity
Select external power source to determine capacity
Select external power supply to determine capacity and model

♦ Actual measurement and detection function:
It can simultaneously measure 23 electrical parameters
Ua, Ub, Uc, Un, Ia, Ib, Ic, In, Pa, Pb, Pc, ∑ P, Φ a, Φ b, Φ c, COS Φ a, COS Φ b, COS Φ c, F. After range expansion, the measurement is expanded to any value.
♦ look up the records:
It can save the rated parameters and no-load, load test records and results of hundreds of transformers, without loss in case of power failure, and can check the test records of multiple times at any time
♦ On site printing:
This instrument is equipped with a micro printer, which can print various test data and results on site at any time, making it very easy to use

Technical indicators
1 Basic testing items
(1) The three-phase method can be used to simultaneously measure, automatically display, and record the following ten values
<1> Three phase effective voltage: Ua , Ub , Uc
<2> Three phase effective current: Ia , Ib ,Ic
<3> Three phase average voltage: Ua , Ub , Uc
<4> Three phase power: Pa,Pb,Pc
<5> Power frequency: F
(2) Automatically calculate and display and record the following values
<1> Three phase average voltage: Un
<2> Three phase average current: In
<3> Phase wise power factor of three-phase: COSΦa , COSΦb ,COSΦc
<4> Three phase total power: ∑ P

2 Range Range
(1) Basic range
Voltage: 20-450 (V)
Frequency: 45-65 (Hz)
Current: 0.3-60 (A)
Power factor: 0.1-1.0
Capacity measurement range: can directly measure the capacity of S7, S9, S11 series power transformers; The scope of judgment can also be expanded based on transformer industry standards, enterprise standards, or special transformer standards.
(2) Expand range
Voltage and current can be expanded to any desired value through voltage transformers (PT) and current transformers (CT), and other quantities can be automatically expanded according to the magnification of the transformers.

3 Measurement accuracy
Within the range under standard conditions)
Voltage (true effective value): 0.2 level
Current (true effective value): 0.2 level
Frequency: 0.1 level
Impedance voltage: 0.2 level
Short circuit impedance: 0.2 level
No load loss, load loss: When COS Φ ≥ 0.5, level 0.2
When 0.5>COS Φ ≥ 0.2, level 0.5
Power factor: same loss
