Digital Tapchanger Control for transformers and regulators

The TCC300 is a dedicated controller for metering,

monitoring, and operational control of step-voltage load tap

changers. The TCC300 is a microprocessor-based package

suitable for substation transformers with on-load tap

changers. The TCC300 can be easily integrated to replace

electromechanical on-load tap changer controllers or for

new installations requiring state-of-the-art controllers.

The TCC300 provides reliable operation with expanding

capabilities such as means to address distributed

generation and cyber security requirements.

Application

REG630 has been designed to be the main

protection for synchronous generators, offering

full protection during start-up and normal run

for both the generator and the prime mover.

The comprehensive generator management relay

is typically used in small and medium-sized diesel,

hydroelectric, combined heat and power (CHP),

and steam power plants. REG630 offers one

predefined configuration, intended for directly

connected generator sets. REG630 has been extended with low-voltage

ride-through, reactive power undervoltage and

voltage vector shift protection to further ensure

grid stability and reliability, and thus avoid grid

collapse. The low-voltage ride-through protection

allows monitoring of distributed generation

during low-voltage fault ride-through, in order

to determine whether and when to disconnect,

for instance, a solar or wind farm from the grid.

Also the reactive power undervoltage protection

does the same but specifically at the grid

connection point, whereas the voltage vector

shift protection detects islanding from the grid.

An optional RTD/mA module offers eight

analog RTD or mA measuring inputs and four

mA outputs. The RTD and mA inputs can be

used for temperature measurement of generator

bearings and stator windings, thus extending the

functionality of the thermal overload protection

and preventing premature aging of the generator

windings. They can also be used for measuring

the ambient air or coolant temperature. The four

mA outputs can be used for transferring freely

selectable measured or calculated analog values

to devices provided with mA inputs.

Generator protection and control REG630

REG630 has been designed to protect small and medium-sized power generators

and power generator-transformer blocks in utility and power distribution systems.

to devices provided with mA inputs.

Product highlights

• Extensive range of protection functionality

the latest grid codes for higher grid stability and reliability

Application

REM630 has been designed to be the main

protection for both asynchronous and

synchronous motors and their drives, offering

full protection during motor start-up and normal

drive operation. The comprehensive motor

management relay is typically used with circuit

breaker and contactor-controlled, medium-sized

and large motors with varying load in drives such

as pumps, fans, compressors, mills and crushers.

REM630 offers two predefined configurations,

of which one is intended for medium-voltage

asynchronous motor applications and the other

for asynchronous and synchronous motor

applications requiring differential protection.

An optional RTD/mA module offers eight

analog RTD or mA measuring inputs and four

mA outputs. The RTD and mA inputs can be

used for temperature measurement of motor

bearings and stator windings, thus extending

Motor protection and control REM630

REM630 has been designed to protect medium-sized and large asynchronous

and synchronous motors in the manufacturing and process industry.

Product highlights

and normal run, with protection and fault

clearance also in abnormal situations

• Extensive motor protection for medium-sized

and large asynchronous and synchronous

motors requiring differential protection

• Extensive motor supervision capabilities via

RTD and mA measurements

 The RTD and mA inputs can be
