Functions

• Directional and non-directional overcurrent protection. Consequently, with additional functions
• Detection of ground faults of any type in compensated or isolated electrical power systems. Specifically, using the following functions: 3I0>, V0>, transient ground fault, cos φ, sin φ, harmonic detection, dir. detection of intermittent ground faults, and admittance
• Optimized operating times thanks to directional comparison
• Motor protection functions: Startup time supervision, thermal overload protection for stator and rotor. Moreover, restart inhibit, unbalanced-load protection, and load-jam protection
• Stator and bearing-temperature monitoring. Especially, via temperature sensors with an external RTD unit
• Sensitive ground-fault protection (directional, non-directional) to detect stator ground faults
• Controlled automatic reclosing of overhead line sections
• Overvoltage and undervoltage protection
• Frequency protection and rate of frequency change protection for load-shedding applications
• Underfrequency load shedding in case of underfrequency. Additionally, taking into consideration changes in feed conditions due to decentralized power generation
• Power protection, configurable as active or reactive power protection

Availability: Available in Mumbai via trusted suppliers, with fast delivery and support.
