Hey there! As a supplier of primary current injection test sets, I often get asked about the price range of these nifty pieces of equipment. Well, let me break it down for you.
First off, what exactly is a primary current injection test set? It's a crucial tool used in the electrical testing industry. These test sets are designed to inject a known current into a circuit or electrical device to test its performance, accuracy, and safety. They're used in a wide range of applications, from testing protective relays in power systems to verifying the functionality of electrical meters.
Now, onto the price range. The cost of a primary current injection test set can vary widely depending on several factors. One of the biggest factors is the capacity of the test set. Generally, the higher the current capacity, the more expensive the test set will be. For example, a basic test set with a lower current capacity, say up to 100A, might cost anywhere from a few hundred dollars to around a thousand dollars. These are usually more suitable for smaller-scale testing jobs, like testing residential electrical circuits or small industrial equipment.
On the other hand, if you need a test set with a higher current capacity, like 500A or more, you're looking at a significantly higher price tag. These high-capacity test sets can cost several thousand dollars, sometimes even reaching up to tens of thousands of dollars. They're used for more complex and large-scale testing in power plants, substations, and industrial facilities.
Another factor that affects the price is the features and functionality of the test set. Some test sets come with basic features, such as simple current injection and measurement capabilities. These are more budget-friendly options. However, if you want a test set with advanced features like digital displays, programmable settings, and the ability to perform multiple types of tests, you'll have to pay more.
Let's take a look at some specific types of primary current injection test sets and their price ranges.
Box-type Primary Current Injection Test Set
The Primary Current Injection Test Set Box-type is a popular choice in the market. These box-type test sets are known for their compact design and ease of use. They're suitable for a variety of testing applications, both in the field and in the laboratory.
The price of a box-type test set can vary depending on its current capacity and features. A basic box-type test set with a lower current capacity might cost around $1,000 - $2,000. These usually have simple analog controls and basic measurement capabilities. However, if you opt for a box-type test set with a higher current capacity and more advanced features, like a digital display and programmable settings, the price can go up to $5,000 or more.
AC/DC Primary Current Injection Test Set
The AC/DC Primary Current Injection Test Set is another type of test set that offers more flexibility. These test sets can inject both AC and DC currents, which makes them suitable for a wider range of testing applications.


The price of an AC/DC test set is generally higher than a single-phase (either AC or DC only) test set. A basic AC/DC test set with a moderate current capacity might start at around $2,000 - $3,000. However, if you need a high-capacity AC/DC test set with advanced features, such as the ability to perform complex waveform testing and high-precision measurements, the price can easily exceed $10,000.
3000A Split Current Tester
The 3000A Split Current Tester is a specialized test set designed for high-current testing. With a current capacity of up to 3000A, it's ideal for testing large electrical equipment and power systems.
Due to its high current capacity and specialized design, the 3000A split current tester is one of the more expensive options in the market. The price of a 3000A split current tester typically starts at around $15,000 and can go up depending on the features and additional accessories.
It's important to note that these price ranges are just estimates. The actual price can vary depending on the brand, quality, and where you purchase the test set from. When buying a primary current injection test set, it's always a good idea to do your research, compare different models and prices, and consider your specific testing needs.
In addition to the initial purchase price, you also need to consider the long-term costs. This includes maintenance, calibration, and the cost of any additional accessories or spare parts. Some test sets might require more frequent calibration to ensure accurate measurements, which can add to the overall cost over time.
So, if you're in the market for a primary current injection test set, take the time to evaluate your requirements and budget. Whether you're a small electrical contractor or a large power utility company, there's a test set out there that's right for you.
