necessary up to 6 cooling levels can be activated.
As an alternative to direct measurement, the U, I, tap
position and cos(ϕ) value can also be transmitted to
the REG-D via either IEC 61850 or by mA inputs,
thereby eliminating the need for CT and VT cabling to
the relay.

The PAN-D relay is used to independently monitor the

control voltage and to supervise signals from the relay
to the tap changer.

3.2 Transducer mode

The values of all relevant variables of a three-wire,
three-phase system with balanced or unbalanced load
are calculated from the measured CT & VT inputs.
All of the measured and calculated values can then be
viewed on the LCD display, or transferred by analogue
signal and SCADA connection.

Connecting transformers in parallel

Each regulator is capable of operating in parallel with
up to 9 other regulators, without the need for
additional components.
A number of different parallel control schemes are
available, fitting for transformers that operate in
parallel on a single busbar, as well as those that are
feeding the same grid from different substations.
Parallel control schemes are listed in Table 1 below:

autonomous add-on monitoring unit.
The Transformer Monitoring module collects and
calculates information about the condition of the
transformer and tap changer.
The hot-spot temperature is calculated in accordance
with IEC 60354 and IEC 60076, and is used to
determine the transformer’s loss of life.
Up to 6 groups of fans and 2 oil pumps can be
controlled to regulate the temperature of the
transformer. The operating times of the fans and
pumps are stored for maintenance purposes.
Oil temperature is measured either directly as a PT100
input or via a mA transducer, and also be recorded
using the Recorder mode.
A total of three analogue input slots are available in

temperatures, oil levels, gas levels, and so on.
Please refer to characteristic group 'E' in the Order
specifications for a list of the combination options.
The parameters for the PAN-D monitoring unit are set
either directly through the unit's interface or by using
the keyboard and display of the regulator.

Several regulators need to be interconnected in a COM2 in the terminal compartment can be used to
network when transformers are connected in parallel. connect a modem, a COM server, a PC or a DCF77
receiver.
The ΔI*sinϕ, ΔI*sinϕ (S) and Master-Follower parallel
programs can only be implemented through the

The REG-D and the PAN-D have two RS232 serial Number of data Data bits: 8
interfaces with three connections (COM1, COM1-S, bits/protocol Parity: even, none
COM2). COM1 is the parameterisation interface, while
COM1-S is an alternative connection option for COM1. Transmission rate 1200, 2400, 4800, 9600,
bit/s 19200, 38400, 57600, 115200
COM1 has priority, meaning that when COM1 has a
connection, COM1-S is switched off. Devices HANDSHAKE RTS / CTS, XON / XOFF, delay,
connected to COM1-S do not have to be physically none
disconnected. This enables COM1-S to function as an
alternative remote parameterisation interface that is
only active when parameters are not being set locally.
COM1 can also be configured as a USB port (optional).
