Dear fellows,
This is the most comprehensive online training of Testing Commissioning ZIV Relays . Here you will learn all thing about test ZIV relays
Our course is divided into tow main sections
We talk in the first section about the IED generically called IRV integrates protection, control and metering functions for a great
variety of applications, such as feeders, machine lines, frontier points, etc. These IEDs use the
most advanced digital technology based on a potent microprocessor and DSPs that
incorporate Directional and Non-Directional Overcurrent Protection, Overvoltage,
Undervoltage, Over / Underfrequency, Synchronism, Power Inversion, Thermal Image,
Recloser function and others.
IRV systems are designed for medium voltage lines, transformers, generators and feeders in
general where a protection, control and measurement device is required.
In the second section we will talk about The generic name RTV groups equipment that include tap changer control functions for power
transformer voltage regulation. This is leading-edge technology based on powerful
microprocessors and DSP’s.
RTV systems are used in applications where constant voltage level must be maintained without
service interruption. Voltage is regulated from voltage and current measurements at power
transformer terminals through current transformers (CTs) and voltage transformers (VTs),
sending command signals to the applicable transformer tap changer to raise or lower the
voltage to set-point value.
