ZIV e-NET FLEX family suite:

all protection functions

ZIV IRL

Compact Feeder Multifunction ​solution for MV switchgear, ​with Load Shedding Function to ​ensure the stability of the system, ​Back-Up performing capability in ​HV lines and powerful built-in ​Control Logic Module.

ZIV IRS

Self-powered Overcurrent and Breaker Failure Protection Relay with Harmonic Blocking

NEW DISTRIBUTED BUSBAR

DIFFERENTIAL PROTECTION WITH PROCESS BUS

• Based on the latest standards for Process Bus (IEC 61869-​9 SV, IEC 61850-8-1 & 9-2 GOOSE, and PTP IEC 61850-9-3)
• PRP or HSR redundancy between Central Unit and Bay ​Units
• Bay units as Protection and Control IEDs. Very cost-​effective for MV busbar differential protection
• Cybersecurity in accordance with IEC 62351, IEC 62443 ​and IEEE 1686-2013 standards.

Line Differential Protection with Distance Backup

DLF

Both units are suitable for lines of any voltage level, overhead or under ground, multiterminal, and single or parallel circuits.

​

• DLF-A: for single breaker​

• DLF-B: for double breaker or breaker-and-a-half, when CTs are at the line side (1 single set of 3 CTs)​

Distance Protection

ZLF

Suitable for lines of any voltage level, single or double circuit breaker with any configuration: overhead or underground, single or parallel circuits​

• ​ZLF-B: for single breaker​

• ZLF-C: for double breaker or breaker-and-a-half​

Transformer Protection 

IDF

for two to four winding transformers or autotransformers, of any voltage level, with single or double circuit breaker.

• IDF-A: for two windings transformers
• IDF-B: for up to three windings transformers
• IDF-E: for up to four windings transformers, or three windings transformers with one winding on breaker-and-a-half

​

Feeder Protection

IRF

for distribution feeders, transformers and generators, transmission line backup, and BCU (Bay Control Unit for single or double circuit breaker).

• IRF-A: MV Feeder Protection & Control
• IRF-B: double breaker or breaker-and-a-half BCU
• IRF-C: general alarms BCU / I/O Box
• IRF-D: single breaker BCU
• 
  
• 
  

Automatic Voltage Regulator 

RTF

for up to 5 power transformers in parallel.

IRL-F

• Compact Feeder Multifunction solution for MV switchgear, with Load Shedding Function to ensure the stability of the system, Back-Up performing capability in HV lines and powerful built-in Control Logic Module
  
• 
  
• 
  

IRS 

Where dependable auxiliary power source is not available, the IRS Relay can be energized either directly from Main Current Transformers, AC/DC Auxiliary Voltage or through the USB Front Port.

A complete SAS for three solar parks capable of generating 150MW

SAS | Liister Drive Stability Project

A project in collaboration between the ZIV team of experts in Substation Control and RTUs located Newcastle (UK) and the experts in protection and control systems at ZIV ​headquarters. The project consisted in a connection of a Stabilizing Synchronous Condenser in the National Grid transmission system.

It included the protection and control of the transformer both for the 275Kv as for the 13,8kV part considering also the necessities of the controller of the SSC device itself. The ​direct client was the British company NRS Group and the owner of the project was the UK’s subsidiary of Nordic company Statkraft who accepted the ZIV IEDs, systems and ​communications protocols in the tendering phase.
