When you are choosing a rental, you need to make sure it will work for your needs. You will want to know the maximum output current, for example. You also want to know which functions and options it might have available for you to use.

Make sure that you consider the size of the device and just how easy it will be for
transportation and getting into different areas that you need to test. There are,
fortunately, a range of options and sizes on the market.

When you are making your choice, you will want to check to see all of the various
features offered on the machine to see if it will meet your testing needs or not. Make
sure it will work with the type of testing you plan to be doing, and be sure you or
someone in your facility knows and understands how to use the device properly. You want to make sure that you are getting accurate results, naturally.

Some of the options available can test the relay protection systems, as well as their
current transformers at the same time. They may also have built-in timers that can be used to record protection relay operations.

Many of the options available today are self-contained and easy to use by a single
person. They also tend to be rugged, which means it is possible to use them in many
environments without worry. Some options from Megger have a handheld controller and an expandable cable so the operator can close to a protective relay. This could be something that would be beneficial for you. Some might also have a separate auxiliary voltage output, which can be used for testing the voltage operated relay coils. This could also be used for checking magnetization characteristics for current transformers.

A primary current injection test set helps to provide technicians and operators with a
means of keeping their electrical systems running optimally. These, along with other
types of testing sets, are essential for proper performance. The primary current injection test set will check to make sure the circuits are functioning properly.
