Parallel operation with the following existing devices is supported:
▪ TAPCON® 230 pro/expert
▪ TAPCON® 240
▪ TAPCON® 250
▪ TAPCON® 260
▪ TRAFOGUARD® with "Voltage regulation" options package
If you wish to operate several devices in parallel operation with existing de-
vices, you have to activate the TAPCON® 2xx retrofit function on each de-
vice.
Figure102: Parallel operation of 2 devices with one TAPCON® 2xx. The TAPCON® 2xx retrofit
function must be active on both devices.
To activate the TAPCON®2xx retrofit function, proceed as follows:
ü Reverse prefix of phase angle correction.
1. Go to Settings > Parameters > TAPCON® 2xx retrofit > TAPCON® 2xx
retrofit.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.
7.7.4 Detecting parallel operation via group inputs (optional)
You can control up to 16 transformers connected in parallel in one or 2
groups without detecting the system topology.
The devices in parallel operation only use the information communicated by
devices in the same parallel operation group via CAN bus.
You can use the PARALLEL GROUP 1 and PARALLEL GROUP 2 inputs to
assign the device to a parallel operation group. If you create a signal at both
inputs, the device is assigned to both parallel operation groups.
If no parallel operation group is assigned to a device, it doesn't take part in
the parallel operation and undertakes its own voltage regulation.
