Digital protection, automation, measurements, control, registration and communication.

CZIP-PRO is a new generation of the CZIP digital protection relays IED family produced since 1995. Digital protection CZIP-PRO is developed by Relpol engineers in cooperation with Institute of Power Engineering at the Poznan University of Technology (prof. Jozef Lorenc research group).

 

CZIP-PRO IED is designed to handle protection, automation, measurements, control, registration and communication functions in the power utility substations.

The main feature of the CZIP-PRO  IED is the possibility to adjust its functionality to the substation bay in which it is operating.CZIP-PRO supports all MV switchgear bay types (ATS control is supported by the CZIP-2R PRO).To reduce the amount of time needed for the setting up CZIP-PRO comes with the predefined settings.

Protection Relay for Medium Voltage switchgear and ATS support
CZIP-PRO is dedicated to operate in the following MV substation bays:

	Feeder bay
	Feeder bay with power generation
	MV side of the 110 kV transformer
	Capacitor bay
	0.4 kV side of the 110 kV transformer
	Grounding transformer in the compensated network
	Grounding transformer in the network with the neutral earthing resistor
	Grounding transformer in the network with choke/resistor parallel system
	Voltage measurement bay
	Bus coupler bay
	110 kV side of the 110 kV transforem

 CZIP-2R PRO for Automatic Transfer Switch (ATS)  

CZIP-2R PRO is dedicated for automatic trasfter switch function in the medium voltage power utility substations. Both, the power reserve and spinning reserve systems are supported.

 

Functions:

Solid-state undervoltage

Solid-state overvoltage

Residual voltage control

Voltage difference control

Permanent ATS blockade

Temporary ATS blockade

Reliable and easy to use operating system

 

CZIP-PRO operating system is build on the dedicated Microsoft Windows® CE Embedded system.

 

The use of the Microsoft Windows® CE Embedded system allowed us to design an attractive and easy to operate graphical user interface.
Big screen with GUI

 

7" LCD screen allows for the access to all settings and parameters readout in a clear and intuitive way. The device functions are logicaly grouped to simplify operations.

 

Configuration of all parameters is possible directly on the CZIP-PRO screen.
Modern design has been combined with a durable cast metal housing, to ensure safety. Thanks to the screw connection terminals installation of the unit has been significantly simplified.

 

Communication interfaces:

USB

2 x RS-485

Ethernet 10/100 Base-TX

Fiber Optics (option)

 

Communication protocols:

DNP3.0

IEC60870-5-103

IEC60870-5-104

Modbus® ASCII / RTU

 Quality confirmed by the independent tests

 

CZIP-PRO has undergone the number of specialized tests in the independent laboratories that confirm the product highest quality.

 

Conducted tests:

EMC

Mechanical Exposure

Climate Exposure
Protection Relay IED CZIP-PRO contains what is most important to the power protecting apparatus. The device has been implemented with proven algorithms and reliable protection criteria, including ground fault protection algorithms developed at the Institute of Power Engineering at the Poznan University of Technology (prof. Jozef Lorenc research group).
