CSP transformer A CSP transformer can be generally defined as a Completely Self Protected device, also known as self-protection transformer, and it is a pole mounted transformer. It is common practice for a CSP transformer to utilize its secure methods and features to guard against harm, and during the installation process, you won't need to install any specialist safety features, which will save you both time and money in addition to eliminating a potential hassle.
