Motorvision (MV2)

Motorvision is our flag ship motor protection and control relay having supplied more than 50,000 units to oil, gas and petrochemical sites worldwide since its introduction in 1997.
Used for comprehensive intelligent protection and control of all LV and MV 3ph motors, whether electrically or mechanically held DOL, 2 speed, reversing drives and start/delta starters.

Motorvision has been used in critical applications, such as circulating cooling systems for nuclear fueled generating stations because of its long service history and robust immunity to radio frequency interference.

Motorvision’s comprehensive protection functions cover the following ANSI numbers:

screen-shot-2016-12-14-at-16-02-55

 

Motorvision is fitted with a graphical lcd which displays the energising current of a motor during starting and makes the relay extremely easy to program, operate and to use.

Motorvision is designed as the primary component integral for any intelligent protection and control system, Motorvision can be equipped with dual communication ports even simultaneously operating over different protocols.

With a proven track record and guaranteed long operational life, it is the safest choice for high-value and high-specification motor protection.

6 or 12x RTD/PTC/NTC
12 or 24x DI
4 or 8x DO
Integrated Vertical or Horizontal Display
Remote Vertical or Horizontal Display with 35mm DIN mounting relay body


Advanced Motorvision2 (AMV2) –
Motorvision, intended for breaker applications and equipped with dual channel trip circuit supervision (TCS) in a large 192mm(w) case.

Motorvision2 with RTDs (MV2-XRTD) – Motorvision with 6 or 12 channels of RTD inputs in a large 192mm(w) case.

 

Due to this modular construction, Motorvision can also be equipped with a combination of hardware to suit almost any requirement, almost too long to list.

For instance coupling AMV2 with 3-ph VT inputs and 6x channel RTDs, with remote display and in a variety of orientations.

 

Motorvision Drawout (MVD) – Motorvision with the option of 9 channels of RTD inputs in a withdrawable 150mm or 200mm(w) case with self-shorting CT inputs

MVD can be equipped with IEC61850 communications
