Testing Commissioning Protection ZIV Relays

Testing and Commissioning ZIV Relays ( 7IRV - RTV )

Ratings: 4.89 / 5.00

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.
