Product Description

China supplier Standard voltage transformer price 

Application
Standard voltage transformers are mainly used as voltage transformer calibration standards in the error test of transformers.
35kV, 0.05 level voltage transformer is a high voltage level, high accuracy voltage transformer, which can be used to verify 35kV, voltage transformers below 0.2 level, and can carry 0.25VA secondary load when the secondary voltage is 100V .
Remarks: Our company also has 220kV, 330kV, 500kV, 1000kV standard voltage transformer (support customization)
Hot Tags: precision potential transformer, calibration voltage transformer, standard potential transformer, standard PT, high precision voltage transformer, self-boosting precision voltage transformer
Features
1. The terminal of the standard voltage transformer adopts plastic terminal to eliminate potential safety hazards;
2. Compact structure, small size and easy to carry;
3. Simple wiring operation;
4. It is suitable for on-site use, and can also be used as a standard voltage transformer and test transformer in the laboratory;
5. The standard instrument transformer with 5VA secondary load can be customized, and the standard instrument transformer with conventional 0.2VA secondary load can be customized.

Technical index
1. Power: 200VA
2. Rated voltage ratio: 35kV /100V,35/kV/100/V,35/kV/100/3V
3. Accuracy level: Class 0.05, means that under rated load, when the voltage is within the range of 80%Un to 120% Un, the ratio error is not more than 0.05%, the angle error is not more than 2', when the voltage is 50% Un When the voltage is 20% Un, the ratio difference is not more than 0.075%, and the angle difference is not more than 3'. When the voltage is 20% Un, the ratio difference is not more than 0.1%, and the angle difference is not more than 4'. (The actual error is not more than 60-70% of the error limit)
4. Test voltage: Primary winding withstand voltage of 1.2Un, 1 minute, secondary winding to ground, power frequency withstand voltage 2kV, 1 minute
5. Rated frequency: 50Hz
