Product Description
The Transformer Short-Circuit Impedance Tester is a new generationof transformer parameter testing equipment developed independently by our company.It is used for low-voltage short-circuitimpedance measurement of main transformers of 35kV and above under field and laboratoryconditions.
Short-circuit impedance is an important parameter of transformers.The short-circuit impedancemethod is a traditional way to assess winding deformation.According to GB1094.5-2003 andIEC60076-5:2000,the change in short-circuit reactance is the sole criterion for determining whetherthe transformer winding is deformed. 1. Three-Phase Short-Circuit Impedance Measurement;
2. Single-Phase Short-Circuit Impedance Measurement;
3. Zero-Sequence Impedance Measurement;
4. Uses AC220Vlow-voltage power supply;
5. One-time wiring;
6. Supports single-phase and three-phase tests;
7. Output current limiting function;
8. No external voltage regulator required;
9. Inductance measurement function;
10. Permanent calendar and clock function;
11. Large-screen color high-resolution touch LCD;
12. 232 interface for external expansion;
13. Built-in printer:Can print displayed data;
14. Built-in non-volatile memory:can store 160 sets of measurement data;
15. USB interface:For data transfer and retrieval.
1. Voltage(automatic range):15~400V±(readings×0.2%+3digits)±0.04%(range)
2. Current(automatic range):0.10~20A ±(readings×0.2%+3digits)±0.04%(range)
3. Power:COSφ>0.15 ±(readings×0.5%+3digits)
4. Frequency(power frequency)45~65(Hz) Measurement range:±0.1%
5. Short-Circuit Impedance:O~100% Measurement range:±0.5%
6. Repeatability Stability:Ratio error<0.2%
7. Instrument Display:5 digits
Other Instrument Parameters
1. Instrument protection current:When test current exceeds 18A,the instrument's internalrelay disconnects for over-current protection
2. Ambient Temperature:-10ºC~40ºC
3. Relative Humidity:≤85%RH
4. Operating Power:AC 220V±10%50Hz±1Hz
5. Dimensions:380×260×120mm
6. Weight:4.5Kg(excluding test lines).
Q1:Is your company a sales or a manufacturer?
We are an integrated trade and manufacturing company with our own factory.
Q2:If we need to customize our own brand or if there are special requirements for the built-in software of the machine, can it be customized?
Yes, we accept OEM/ODM/OBM and can customize the built-in software of the product according to the customer's special requirements.
Q3:What is the usual lead time? How long can we receive the order after placing it?
In normal circumstances, products in stock can be received within 5 to 7 days via the fastest international express. Other situations may vary depending on the quantity of products ordered, whether there are special customization requirements, and the delivery time chosen.
Q4:How can we ensure that the product will not be damaged during transportation, considering the large size of the product?
We have professional internal and external packaging to ensure the safety and stability of the products during transportation. For fragile or other special parts, we will include an extra set to ensure that the customer can use the product immediately upon receipt.
Q5:How do you handle after-sales service? What if there is a quality problem with the product or if the customer does not know how to operate it?
For quality issues that are not caused by human error, we provide a one-year warranty from the time the product is delivered, and lifetime technical support. Other after-sales issues will be addressed by our professional technical staff within 24 hours. The product comes with a user manual and an operation video.
