Decoding the concept of "VAper" (VA): Why is the burden in the transistor?
Dangerous consequences of mismatch: beyond a simple error
- Real load more than CT's nominal load: This is the most dangerous scenario. Under normal circumstances, there may be no problem, but at the moment of error, it can saturate the initial flow of the core. The protective relay sees the error flow much less than the actual value, it does not operate at all or works with high delay. Result? Severe damage to power transformers, generators, cables and other expensive network equipment.
- Real load much less than CT's nominal load: In this case, although safety is not compromised, you have paid the cost of a larger and more expensive transistor for no reason. This unhealthy choice leads to increased project costs and occupy more space in the powerboard.
When standard solutions are not sufficient: Need to make a custom trans -stream
- The high distance between CT and control panels: In large industrial plants, electricity posts or power plants, the CT distance mounted to the control room where the relays is located can reach tens or hundreds of meters. The resistance of these long cables imposes a significant burden on the CT that should be seen in the initial calculations.
- Connecting multiple devices to a CT: In some designs, a trans -current task of feeding a protective relay, a digital meter, an analogue amp and a converter. The total load of these devices may be a non -standard number such as 85VA or 120VA.
- Complex protection systems: Advanced protective designs such as differential protection require the accurate adaptation of CT specifications to two or more points of the network. In these cases, the construction of a custom VA trans -stream is a requirement to achieve proper functioning.
- Optimization and Replacement Projects: When upgrading an old system, you may encounter non -standard current trans -transit transduses that are no longer produced. In this case, the only way is to build a transition of 1 to 2V current to your order to accurately replace the old piece.
Aria Engineering Process for Birch Converter to build a transition of 1 to 2 voltamper on your order
Step One: Technical advice and careful analysis of the needs
- What is the exact load of each secondary equipment attached? (Relay, meter, etc.)
- What is the length and cross -section of the cable relationship between CT and equipment?
- What is the precision required for the Metering and Protection Class?
- Maximum possible short circuit current at the installation site?
Step Two: Engineering Design and Core Calculations
- Care cross -sectional calculation: Based on the required voltage and knee point required for the protective class, the magnetic core cross -section is calculated so that under no circumstances, even in the highest error, the nucleus is saturated with the low,
- For protection cores, the kernel behavior in the saturation area is more important.
- Calculate the number of primary and secondary rounds: To achieve the precise conversion and accuracy class, the number of coils is calculated and designed.
Step Three: Selection of superior raw materials and accurate production
- Coils: Pure copper is used with a heating insulating lacquer F or H which is highly resistant to heat -induced heat.
- Insulation: The best insulation materials for insulation between the layers and between the primary and secondary coils are used to ensure complete electrical safety. The coils are fully assembled to be resistant to severe dynamic forces caused by short circuit.
Step Four: Comprehensive Quality Control Tests and
- Testing Testing and accuracy Error: To ensure the accuracy of the transformer performance in the accuracy class defined.
- High voltage test (HI-Pot): To confirm the strength of the insulation system.
- Knee point test (for protection cores): Secondary: To check the quality of connections.
This process guarantees that the delivery product is exactly what you have registered the transition of 1 to 2 voltamper.
