Integrated Speed, Voltage and Synchronism System
Microprocessed digital equipment which has the function of controlling synchronous machines.
The flexibility in the adjustment of the parameters and topology of assembly associated with the possibility of creating logical functions allows its use in a wide range of applications.
For excitation currents up to 15A, there is the option of using an incorporated power module (GPRI2000-15), employing technology IGBT.
It also allows controlling external power modules with topologies using IGBT or thyristor.
The equipment GRTD-2000 has several logical blocks and functions.

FIELD APPLICATION RELAY GCDT-02E
Device for control of synchronism of synchronous motors, through control of field application, based upon frequency of slip of rotor and polar angle.
It allows applying excitation in exciter field already in motor start.
It executes the crowbar function, placing the start resistance in parallel with field during the start.
Compact and resinous construction, being able to be installed in the rotor of the brushless motor.
Handles a wide range of variation in the power supply voltage.

System for control of application of short circuit in rotor of synchronous motors during the start.
Compact and resinous construction, being able to be installed in the rotor of the brushless motor.
It has internal RC circuit to reduce dv/dt, thereby avoiding accidental start.
It uses two GCDT01 modules which can be distributed in an equidistant way in the shaft, facilitating its balancing.

Unit supplying DC of wide application used as a battery charger or as a source of voltage.
Operated in parallel, GCB will ensure supply to consumers even after disconnection from the battery.
As a source of voltage, GCB maintains connected to the consumers with a fixed DC voltage, 12 or 24 Vdc.
Single-phase input of: 220Vac
Current available: 10Adc, 20Adc or 30Adc

STATIC CONVERTER FOR POWER SUPPLY OF AIRCRAFT 400HZ
GSPU Grameyer is a static converter of energy which from the conventional power supply network, 220/380/440Vac 50/60Hz, makes available three-phase power supply 115/200Vac in 400Hz intended to supply the energy requirement for aircraft.
It can be used in boarding bridges, mobile support units on the runway or in maintenance hangars. With output power capacity of up to 180kVA, with option of supplying 28Vdc integrated.
The control system is bases in philosophy SVM (Space Vector Modulation), which optimizes performance reducing harmonic distortion, implemented totally with digital technology, which, besides the control loop, includes automatic protection, adjustments of parameters and readings of output conditions, through a user-friendly interface. Developed and manufactured fully by Grameyer with its own technology, which makes available, besides the warranty, technical support with specialized labor throughout the domestic territory.
