Disorder that often occurs is the short circuit between phase or phase to ground and between the two. Short circuit can cause large currents that can damage equipment or security systems that needed protection system. The current flowing to the trip coil (TC) is the direct current from the storage battery.
Storage battery has an important role in the protection system, resulting in maintaining the reliability of storage battery protection system must be properly maintained.

Protection system in addition to securing the installation of equipment to interference, it also serves to localize the disorder. If an interruption occurs in a part of the installation, the protection system is only going to trip PMT adjacent to the disorder and not widespread.
