Engga EVC800I AVR (Automatic Voltage Regulator) Generator Parts Replacement
The EVC800i is a 3 Phase full wave, pulse width modulated type of Automatic Voltage Regulator for regulating the voltage
of Brushless Generator.
Excitation power can be derived from a shaft-mounted 3 Phase permanent generator (PMG) or stator winding or Auxillary
winding. Internal electrical isolation is created between the PMG inputs and sensing inputs of AVR. This isolation with the
PMG assures the performance of the AVR against Non-linear loads and reduces the Radio frequency interference on the
generator terminals. The PMG supply enables the generator to maintain current in a short circuit.
Sensing to AVR is directly from the main winding. This signal is used to control the power fed to the exciter stator (and hence
to the main rotor) to maintain the generator output voltage within the specified limits. Provision is made for the connection
of the remote potentiometer allowing the user to find the control generator output voltage.
Built-up of the generator output voltage is fully under control manner keeping the excitation current within limits and with a soft start.
A frequency measuring circuit continually monitors the speed of the generator to provide low-speed protection to the
excitation system. It reduces generator output voltage proportionally with speed below an adjustable threshold as per volt
per hertz slope. This slope is provided adjustable and adjusted by a DIP adjustment trimmer. In addition to DIP, a delayed
voltage recovery (DWELL) is provided to improve speed recovery time when the generator is used in conjunction with Turbocharge engines. The generator overload circuit cuts off the excitation power in the event of excessive load on the generator or
malfunctions. AVR observes overload condition for 20 seconds and after that cuts off the field voltage.
This condition remains latched until the generator has stopped.
For connecting 2 or more generators in parallel, quadrature droop and analog inputs provide reactive power-sharing
controls.
