NOVAR 2600 Operating Manual
1. General
This manual comprises description of NOVAR 2600 three-phase power factor controllers.
The controllers are based on precise and powerful three-phase measurement & evaluating core and
combine multifunctional panel meter and power quality analyzer with power factor control functionality
in the same box.
The built-in meter can be optionally equipped with memory for datalogging of measured quantities and
various events in the network thus the instruments can be used for long time network data recording.
For on-line monitoring, the controllers can be provided with remote communication interface.
The controllers can be delivered in various modifications : with various numbers of outputs & inputs,
optional datalogging capabilities and communication interfaces. Depending on it the instruments
support only basic functions or additional functions too.
1.1 Common features
Power Factor Control
• individual phase power factor control capability using single- / two- / three-phase capacitors
and chokes
• selectable power factor control strategy : both three- and single-phase control / three-phase
control only / three independent single-phase controls
• up to 18 output sections, relay or solid-state
• controller’s speed of response independently programmable for conditions of
undercompensation and overcompensation
• the preset speed of response increases in proportion to instantaneous control deviation, that
is either with the value squared or in direct proportion to the ratio of the control deviation to
the smallest section value (O
MIN
)
• adjustable control range to reduce the number of control interventions in systems with a wide
control range at high loads
• combined mains compensation & decompensation capability
• selectable two-rate operation controlled with active power level or external signal (optional
input)
• automatic output section recognition, any combination of the output sections possible
• continuously checks output sections in the control process. When failure is detected
repeatedly, disables the faulty section and possibly actuates alarm.
• periodically rechecks the temporarily disabled sections and on positive test result (for example
when replacing a section’s burnt fuse link), it enables them again automatically
• wide assortment of independently settable alarm’s warning and actuation functions
( undervoltage, overvoltage, undercurrent, overcurrent, THDU limit overflow and more )
