The distribution automation controller PZK-56 features the single CPU Module design that is common to the whole PZK-5X family of RTUs. It is designed for the harsh environmental operating conditions experienced by field-installed intelligent electronic devices (IED). The design is ideal for substation monitoring and control and to work with a variety of power system plant including; switchgear, reclosers, ring main units, box type substations, transformers and reactive power compensation capacitors.

The PZK can provide the following features:

• SCADA measurement and control
• Fault recording
• Short circuit fault detection and location
• Overcurrent and low current earth fault protection
• Feeder automation
• Distributed current differential protection
• Distributed remote trip anti-islanding protection
