MR OLTC & TRANSFORMER ACCESSORIES


On Load Tap Changers (OLTC):

VACUTAP VR

The world’s first on-load tap-changer which is maintenance-free up to 300,000 switching operations. Since its maintenance is not time-dependent, your transformer has much less downtime.

VACUTAP VM

Fully retrofittable and 100% connection-compatible with the OILTAP® M, of which there are over 70,000 in existence. All you have to do is dismantle the old diverter switch and fit the new VM® model.

VACUTAP VV

Already operates throughout the world. It’s maintenance-free up to 300,000 operations and suitable for most network applications. Thus your transformer lifecycle costs are reduced significantly.

OILTAP R

The on-load tap-changer for the highest voltages and transformer output rates.

OILTAP M

The on-load tap-changer allowing the widest and most comprehensive scope of applications: From transformers with medium output rates to large power transformers, process transformers subject to the highest levels of stress, special transformers.

OILTAP V

An exceptionally compact on-load tap-changer for tapped transformers with small to medium output rates.


Voltage Regulators & Transformer Monitoring System:

ISM TECHNOLOGY
  • Latest communication technology
  • New intuitive operation, cutting-edge graphical display – ISM® Intuitive Control Interface (IICI)
  • Prepared for new applications and the challenges of the future
  • Maximum operational reliability and data security

TAPCON 240-LV

The “Limit Volt” System for monitoring the regulated distance in a HV transformer. The main functions of the TAPCON® 240-LV are:

  • Monitoring the regulated mains voltage (under- and overvoltage)
  • Monitoring of voltage changes initiated by tap-change operations
  • Monitoring the Electronic motor drive ED (under/overvoltage)
TAPCON 230

Measurement, control and regulation – the TAPCON® 230 voltage regulator provides all these functions in one device. Regardless of whether simple regulation tasks or complex requirements for a modern transformer control device, the TAPCON® 230 can be used flexibly and completes all tasks reliably. It is a real all-around worker that offers the highest level of operating convenience.


MR Motor Drive Tapmotion & Oil Filter Unit

OIL FILTER UNIT OF 100
  • paper filter design to clean the switching oil
  • 2 pump unit designs available
  • combination filter design to clean and dry the switching oil
  • 2 designs for controlling the pump unit
  • control integrated into separate control cabinet
  • control integrated into the ED motor drive
PROTECTIVE RELAY RS2001

The protective relay is designed to protect the on-load tap-changer and the transformer during a malfunction within the on-load tap-changer or the selector switch oil compartment.

TAPMOTION ED

TAPMOTION® ED is used exclusively for operating on-load tap-changers and off-circuit tap-changers in regulating transformers as well as for operating plunger-core earth-fault neutralizers.
