About the PZK-560Z
Based on the PZK-56A device, the PZK-560Z column-mounted switch terminal device is designed for distribution overhead line switch monitoring and control. It features flexible power supply based on the line voltage optionally backed-up with maintenance-free leadacid batteries, super capacitors or lithium batteries
Key features
- Communication with the main substation to monitor and control the overhead line switch status
- Fault location, isolation and supply restoration (FLISR), including low-current earth faults
- Local automation without relying on the distribution network automation master (substation) control
- Distributed protection for overcurrent, current differential and remote trip anti-islanding
- Islanding unbalanced power control and distributed low-current earth fault location and tripping
- Flexible configuration to support 'two remote' or 'three remote' functionality
