ALPISTATIC composition and characteristics

ALPISTATIC includes:

a capacitor bank split into several steps depending on the compensator power rating
one three-pole solid state contactor per step (cutting all three phases)
fan-cooled heat sink on each solid state contactor
standard type and duty type: 3 single phase damping reactors providing protection of the solid state contactor
SAH type: 1 anti-harmonic reactor, three phase, providing protection of the solid state contactor and protection from harmonics
one set of three HRC fuses per step
a control system for the solid state contactors, including:
- a reactive energy controller for automatic control
  - with automatic / manual operation
  - front panel display showing the number of stages operating
  - front panel display of cos φ
  - front panel display of many other electrical parameters (harmonics, etc.)
- microprocessor instrumentation and control board using solid state contactors:
  - triggers and releases contactors within 40 milliseconds max.
  - avoids any transient voltages and currents when steps are triggered or released.
