Transformer regulators for all measurement tasks

REG-DA

With the REG-DA transformer regulator, all measurement, control and regulation tasks for tapped transformers can be achieved. Alongside its basic functions, the REG-DA regulator can also be used as a transducer, recorder, statistical unit, parallel control device and transformer monitor as per IEC 60354 or IEC 60076.

Unique flexibility

Through our many years of experience in the industry, we know that every customer and every project has specific requirements. Accordingly, we have developed the transformer regulator REG-DA in such a way that it can respond very flexibly to these requirements, which is unique in this form. For example, the REG-DA offers a flexibly expandable number of inputs and outputs, a wide range of applications through software features, and free programmability.

Panel mount and Wall mount enclosure

The REG-DA is available with a wall-mounting and panel-mounting housing as well as a DIN rail-mounting device. The shallow depth of the housing also allows applications of the transformer regulator in flat control cabinets or motor drive boxes. The housing is equipped with protection class IP54.

The right control protocol for every application

The communication interfaces of the REG-DA have the possibility of role-based user administration (RBAC) incl. authentication via RADIUS.
REG-DA can communicate with a central control system via various protocols.
The following protocols are available:

  • IEC 60870-5-101/103/104
  • IEC 61850 (Server, Client, GOOSE, 9-2 Sampled values)
  • DNP 3.0 via Ethernet
  • DNP 3.0
  • Profibus DP
  • MODBUS RTU
  • SPABUS
  • LON (on request)

All necessary functions in a single transformer regulator

The functional scope of our transformer regulator is unique. The control of 3-winding transformers, of phase-shifting transformers, of transformer banks and of compensation reactors as well as transformer monitoring is all possible with only one device and one firmware.

Parallel operation with up to 15 transformers

The REG-DA allows parallel operation of up to 15 transformers. The parallel program Master-Follower as well as various programs for circuit reactive current minimization (with and without communication between the controllers) are available. The ParaGramer serves as an aid for the automatic recognition of parallel circuits and for the visualization of the switching states. The ParaGramer maps the switching situation of the individual transformers in single-phase representation and enables automatic detection of parallel operation by evaluating the switch positions.
