1. Let's talk about this product first
1.1 What is a summation current transformer?
You can understand it as a 'current aggregation expert', whose job is to gather the currents from several lines and integrate them into a total current signal. We only need to look at this final reading to grasp the overall current situation of all lines, which is very intuitive and convenient.
This design is particularly practical in many scenarios. For example, when you only need to focus on the total electricity load and there is no need to measure each current separately, using it can quickly grasp the overall situation and save the trouble of measuring one by one, naturally improving management efficiency.
1.2 Positioning of SUM series products
Our HEYI SUM series summation current transformer has been completely upgraded this time! Simply put, it means becoming smarter and more capable than before, not only accurately measuring, but also using it with ease. Even if the current levels on site are different or the voltage fluctuates slightly, as long as their changing rhythms are similar, they can be measured together.
It is precisely because of this characteristic that it is particularly popular in complex industrial settings, providing you with a convenient and reliable solution.
2. What are the outstanding aspects in terms of technology
2.1 High precision, accurate measurement
High measurement accuracy can be said to be the key skill of our series of summation current transformers. Even if there is a slight difference in phase or voltage among several currents on site, it can still accurately measure the total current.
Of course, there is one thing that needs to be clarified first, because its working principle will react to voltage differences, which will bring a tiny error. So, if it's a situation like electricity metering that requires careful consideration and not a single penny to go wrong, it's not very suitable to use it.
2.2 Installing it saves a lot of mental energy
When designing products at HEYI, our first consideration is how to make it easier for everyone to install. For example, the biggest feature of the SUM125 model is its flexibility. It has two installation methods, either by firmly locking it with screws or by directly clamping it onto a standard guide rail. Especially for the installation of guide rails, the operation is super simple. Just align the position and gently push it to install, which is very convenient.
The SUM155 model, on the other hand, places more emphasis on the word 'stability' in its design. It uses four M8 large screws to fix it, specifically designed for situations with high vibration. Even if the on-site equipment shakes violently, it can still stand firmly, ensuring stable measurement data.
2.3 Structural design is sturdy and durable
This series of products has really invested a lot of money in materials, and the overall design is particularly solid, aiming to "withstand and last for a long time".
It can easily withstand situations common in industrial sites, such as fluctuating temperatures, humid environments, or high electrical interference in the surrounding area.
The advantage of this design is that it can ensure stable operation of the equipment throughout the year and is very resistant to manufacturing. It is precisely because it is so reliable that it has become a choice in various industrial scenarios.
3. Where can they all be used?
3.1 SUM125 easily handles industrial lighting monitoring
For example, in the power distribution cabinet of a factory, you want to monitor the total electricity consumption of three lighting circuits, but if each circuit is equipped with a separate meter, it will be too troublesome.
At this point, engineers really like to use our SUM125 summation current transformer. It's not difficult to install at all, just clip it onto the standard guide rail of the distribution cabinet, and it can be connected in just one minute, which is particularly convenient.
Its function is to merge the three currents into one total signal, which is then transmitted to the monitoring system behind it. In this way, the on-site wiring is much simpler, and the entire system looks clean and refreshing. Management personnel can easily see the overall electricity consumption situation in the background, which is particularly worry free.
3.2 SUM155 summarizes the current of wind power plants
Let's take a look at a rather special scenario - a wind power plant. It is necessary to combine the currents generated by many wind turbines in the combiner box for monitoring, but the on-site vibration is particularly severe and ordinary equipment cannot withstand it. So the engineers directly chose the SUM155, which is more robust and installed more firmly, and fixed it firmly on the mounting plate with four M6 screws, completely solving the vibration problem.
In this way, this "hardcore" device can work stably in harsh environments, combining various currents into an accurate total signal and transmitting it to the power plant management system in real time.
4. Summary
To be honest, HEYI has been dedicated to one thing over the years, which is to produce high-performance, sturdy, and durable current transformers for customers worldwide.
This SUM series summation transformer can be said to be our "flagship". It not only incorporates our years of technical accumulation in the field of electrical measurement, but more importantly, we truly understand what our industrial partners need the most.
I hope it can also become a knowledgeable and reliable 'old buddy' around you in the future.
