be viewed on a display, are calculated from these measurements’ results while it is possible to preset
the THD and the CHL threshold levels at which the controller disconnects all compensation sections
thus preventing their damage. Besides that, the most adverse values are recorded into the
instrument’s memory for subsequent analysis.
Besides the power factor capacitors, it is possible to connect power factor chokes (power system
decompensation). Any output can be set as fixed, the two highest outputs can also be used to connect
the cooling or heating circuits.
The controllers come in two basic designs with different numbers of outputs: Novar1106/1206 with six
output relays and Novar1114/1214 with fourteen output relays. The Novar12xx controllers have, as
opposed to the 11xx line, an additional voltage measurement input and a second metering rate input.
Both types of controller have an Alarm relay output that can be set to indicate non-standard
conditions, such as undercurrent, overcurrent, measurement voltage failure, overvoltage, harmonic
distortion preset threshold exceeded, overcompensation or undercompensation, section limit
connection rate exceeded, section outage, backfeed condition (power export) or overheating.
The 11xx and 12xx types of the controller can be ordered in a version featuring an optional galvanic-
isolated RS-485 or Ethernet communication interface. All values measured can be then monitored and
the controller’s parameters set using a remote computer.
1.3 Novar Controller Version “/S400”
Controllers of version “/S400” ( model marking example : Novar-1114/S400) diifer from standard
version of the Novar-1106 / Novar-1114 / Novar-1206 / Novar-1214 models in following aspects :
•
increased maximum power supply voltage up to 500 V, both AC and DC
•
relays’ common contacts isolated, connected to additional terminals
The “/S400”-version instruments can be used at isolated networks (without neutral wire). The other
features are identical to those of standard version.
1.4 Novar-1005 / 1007 / 1005D / 1007D
These models are simplified versions of the Novar1106 / 1114 models. They are built in smaller box
and designed for less demanding applications. Novar1005 features 6 output relays, Novar1007
features 8 output relays.
The “D”-types are designed for mounting on DIN-35 bar.
1.5 Novar1312, Novar1312-3
Novar1312 is designed to provide rapid compensation using thyristor switches. It differs from
Novar1214 in the two following principal aspects:
•
outputs 1 through 12 are transistor-driven
•
control speed for these outputs can be set up to 25 interventions a second
Functionally identical Novar1312-3 farther differs in that it has three current inputs and process sum of
all three phase current signals. Therefore, it allows fast compensation according three-phase power
factor.
Novar1312 and Novar1312-3 specific features are described in a separate chapter. The other features
are identical to those of Novar1214.
