Regulator of jet power RRMG-12

Appointment

• Deduction of the set parameter of a koeffiktsiyent of power.
• Indication and control of pakrametr of a network.
• Ensuring optimum operation of condensers in heavy duty use, including in the modes of an overstrain and in the presence of harmonious sostavklyayushchy.

Application

• In sistekma of automatic control of compensation of jet power in three-phase networks of 0,4 kV with the symmetric, not fast-changing loading, both with existence of garmonicheksky components, and without them.

Principle of work:

• The regulator of jet power RRMG-12 applied in the installations of compensation of jet power (ICJP) is equipped with measuring contours of current and tension. After digital processing of the measured sizes values of power factor, and, by connection or shutdown of necessary number of batteries (steps) of condensers decide on high precision, regulation of jet power is carried out.
• The regulator counts necessary inclusions and shutdowns of steps according to various algorithms:
• • delays on inclusion/shutdown,
  • delays on repeated inclusion,
  • prevention of the resonant phenomena,
  • external sequence.
• The regulator provides the following types of protection of condensers (steps):
• • protection against harmonious distortion of tension,
  • protection against an overstrain,
  • protection against frequent switchings,
  • protection against instant double inclusions.

Advantages

• 12 types of output sequences.
• 12 steps of output contours.
• Display of coefficients of nonlinear distortion of tension and current.
• Display of full power factor of the PF network *
• Displays of the main power factor of the DPF network **
• High precision of measurements, 4th digit display.
• Convenient simple interface in operation.
• Manual and automatic operating mode.
• Automatic mode of calculation of capacity C1.
• Settings remain at loss of tension
