VTE-XXX--2-22 extra energy efficient exciter for critical objects with 100% all systems duplication. With built'in transformerVTE-xxx-xxx-2-22 Extra energy efficient PLC-controlled synchronous motors excitation device for critical facilities and production lines not permissible shutdown the due to failure of a part of equipment. 100% reservation of PLC-control system and thyristors rectifiers. Excitation powered from built-in transformer. Only well-known brands components used in the production. 

Features:
  
  1. Two full-featured PLC-control system
  2. 100% Automatically control system reservation
  3. 100% thyristors (bridges) rectifiers reservation.
  4. Two bridges 3-phase thyristors rectifier, automatically  reservation and switched for best power factor
  5. Built-in transformer UNICORE-technology (no-load current less 0.3A) with two-tapping of secondary winding
  6. IDLE-AC contactor with magnetic latch ( not require power for hold) switch-off transformer automatically for idle-time bridges thyristors rectifier
  7. Sided maintenance 
  8. Small footprint 
Application: 
  1. Critical objects
  2. Continuous production lines
  3. Upgrade existing excitation system 
  4. Hig-h and Low-voltage synchronous motor excitation

Cases

1.Power saving function by automatically power factor correction
2.UNICORE transformer: No-load current less 0,3A
3.Idle AC-contactor with magnetic latch. No power in the ON-state. Switches off the transformer in the absence of excitation.
4.Cooperation rectifiers and transformers with two taps. After the forcing, the main rectifier is connected to the tap of low voltage, so the angle of thyristor control near the minimum, and nearly sinusoidal voltage waveform. As a result of decreasing the iron loss transformer.

Reservation Control Systems
Two full-feature PLC-controlled unit, each equipped with its own set of sensors and power supply. In real-time they exercise mutual control via communication.
In case of violation of the normal functioning of the active PLC, control automatically and smoothly switches to serviceable PLC. 

Reservation rectifier
When a fault is detected thyristors control-channel (delayed conduction or no conduction) main rectifier operation is automatically switched to the forcing-rectifier.
If the fault persists, the exciter continues to work on forcing-rectifier to a scheduled stop. If the fault occurs on the forcing-rectifier, the engine and exciter to switched off.

Package:
1. Exciter VTE-XXX-XXX-2-22
2. User manual
3. CD-disk Ajuster software
4. USB A-B cable

Data Logger. Oscilloscope
The digital control system is provided by the data logger. In the non-volatile memory 31 are stored waveform of events: starts/stops the engine, on/off the power of control system.
Statistical information in the history:
- Total operating time of the control system and the engine
- Quantity of emergency shutdowns of the engine (counters for each type of accident)

Advanced oscilloscope unit 

View waveforms from data logger and statistics possible with Ajuster software (reading data by USB interface) and operator panel (Linux-based, color TFT display with touch-screen). Operator panel, provides extended service for data logging:
  1. Storage waveforms and statistics on the SD-card (can be removed)
  2. Waveform - a continuous record of 30 days (ring-record)
  3. Waveform, and statistics can be copied to USB flash-drive
  4. SSH access to files is available via Ethernet
  5. Using the operator panel, can view the waveform of any event, within an arbitrarily given time interval
