ODEN AT является необычайно многофункциональным переносным проверочным прибором, который способен генерировать ток силой от нескольких сотен до 22000 ампер. Устанавливаемый на тележку ODEN AT легко перемещать с место на место — каждый модуль является достаточно легким для одного человека. Модульная компоновка состоит из блока управления и одного, двух или трёх источников тока.
ODEN AT — Система испытания первичным током
ODEN AT — дальнейшая модификация хорошо зарекомендовавшего себя переносного источника тока серии ODEN производства фирмы “Programma” — воплощает в себе много новых и передовых технических характеристик. ODEN AT является необычайно многофункциональным переносным проверочным прибором, который способен генерировать ток силой от нескольких сотен до 22000 ампер. Устанавливаемый на тележку ODEN AT легко перемещать с место на место — каждый модуль является достаточно легким для одного человека. Модульная компоновка состоит из блока управления и одного, двух или трёх источников тока.
ЛЁГКОСТЬ В ОБРАЩЕНИИ: для того, чтобы совместить многофункциональность системы с легкостью в обращении её создатели уделили первостепенное внимание контрольной панели и интерфейсу пользователя. Для панели управления используются понятные обозначения и она разделяется на несколько секций. Для наиболее часто встречающихся применений существует ряд предварительно запрограммированных установок. Система ODEN AT легка в обращении, вы можете повторить любые испытания, нажав всего одну кнопку.
МНОГОСТОРОННИЙ КОНТРОЛЬ ЗА ГЕНЕРИРОВАНИЕМ ТОКА: время генерирования тока контролируется с помощью встроенного таймера и, кроме того, подачу тока можно прекратить, используя внешнее напряжение или внешний контакт. ODEN AT может выдавать кратковременный ток с помощью одной единственной кнопки, причем, возможно получить последовательность импульсов, при которой как величина импульсов, так и интервалы задаются пользователем. С помощью функции “Удержать” и способности системы подавать кратковременный ток возможно добиться тока нужной величины, избежав при этом перегрева тестируемого объекта. Более того, можно установить необходимый выходной ток, используя всего лишь 1/30 часть тока, от требуемой величины.
ШИРОКИЙ ДИАПАЗОН ИЗМЕРЯЕМЫХ ПАРАМЕТРОВ: сила тока и время выводятся на цифровом дисплее. Может быть использован вторичный измерительный канал для измерения тока или напряжения. Вычисляются и выводятся на дисплей коэффициент мощности (косинус φ), а также фазовый угол. Сила тока и напряжение могут быть представлены в процентах от номинального значения. Быстродействующая функция “Удержание” способна сохранить на цифровом дисплее те кратковременные значения, при которых напряжение или управляющий сигнал поступают на вход “Стоп” и генерирование тока прерывается.
Испытание первичным током и проверка автоматических выключателей: подобные испытания требуют токов большой силы и способности измерять очень короткие импульсы тока и интервалы времени. Система ODEN AT специально предназначена для таких целей. Для измерения времени срабатывания низковольтного выключателя не требуется никаких дополнительных контактов. Тестирование прекращается в тот самый момент, когда главные контакты размыкаются, чтобы отключить ток. Начало подачи тока синхронизируется с точкой перехода синусоиды тока через нулевое значение для того, чтобы обеспечить возможность повторять тест и минимизировать смещение постоянной составляющей.
Проверка трансформаторов тока: при определении коэффициента трансформации по соотношению витков на дисплее одновременно высвечиваются значения первичного и вторичного токов, или коэффициент трансформации. Так как коэффициент трансформации показывается как номинальное значение (например, 1000 / 5), нет необходимости осуществлять дальнейшие вычисления.
Проверка полярности: Показывается сдвиг фаз и чётко обозначается полярность выходов.
Определение активного и полного сопротивлений: нажатием нескольких клавиш ODEN AT может быть быстро и легко превращен в микроомметр. Измерение сопротивления с помощью очень высоких токов является исключительной особенностью системы. Могут быть измерены импеданс, фазовый угол, нагрузка в соединённых цепях, а также другие параметры.
Устройства АПВ и секционные разделители: ODEN AT также может быть настроен на проверку устройств АПВ прямого действия и секционных разделителей. Могут быть измерены пороги срабатывания, частичное и полное время, а также количество срабатываний перед выключением. По выбору пользователя может быть запрограммирована последовательность повторных включений для проверки разъединителей.
Проверка системы заземления и устройств защитного заземления: одним из способов проведения этого теста является подача тока между базовым заземлением и заземлением, которое должно быть проверено, и измерение падения напряжения, а также силы тока в процентах через сеть заземления. Для такого применения предназначена система ODEN AT с источником тока типа “Х”. Защитное заземление должно испытываться при расчетных токах, задача, для которой хорошо подходит эта система.
Тепловые испытания: система ODEN AT идеальна для проведения испытаний на перегрев. Ток может подаваться непрерывно или через запрограммированные интервалы. Время может показываться в минутах и часах, что облегчает проведение долговременных тестов.
Дополнительный модуль: позволяет прогружать выключатели постоянным током (4,5 кА в течении 5 секунд).

Primary Current Injection Test System
ODEN AT
Primary Current Injection Test System
▪▪Most Advanced Primary Current Injection
Test System to simplify all types of switchgear and CT commissioning, ground grid, circuit breaker testing and more
▪▪Modular design to permit optimal user configuration of output current vs. unit size
▪▪Compact transport cart facilitates portability into switchgear rooms with limited space
▪▪Unique I/30 function allows the current to be pre-set using low current to prevent test sample heating, thus eliminating corruption of test result
Description
This powerful test system is designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the turns ratio of current transformers and for other applications that require high variable currents.
The system consists of a control unit together with one, two or three current units. There are three versions of the current unit: S, X and H. The S and X current units are identical except that the X unit has an additional 30/60 V output. The H unit is rated for even higher current. This makes it possible to configure an ODEN AT system in a suitable way. All parts are portable, and ODEN AT can be quickly assembled and connected.
The control unit has many advanced features – a powerful measurement section for example, that can display turns ratio as well as time, voltage and current. A second measurement channel can be used to measure an additional current or voltage. Current transformer turns ratio, impedance, resistance, power, power factor (cos φ) and phase angle are calculated and shown in the display. Current and voltage can be presented as percentages
of nominal value. The fast-acting hold function freezes shortduration readings on the digital display when the voltage or contact signal arrives at the stop input, the object under test interrupts the current or injection is stopped
Application
Primary current injection testing and breaker testing
These tests require high currents and the ability to measure very short duration, current flow. ODEN AT has been designed especially to meet these needs. No extra contacts are needed to measure the operating time of a low-voltage breaker. Testing stops at the instant when the main breaker contacts open to interrupt the current. Output current initiation is synchronized with the currents zero-crossover point to ensure good repeatability and minimized DC offset.
Testing current transformers
For turns ratio testing, the primary current and either the secondary current or the turns ratio are displayed simultaneously. Since the turns ratio is displayed directly as the nominal value (1000/5 for example), no further calculation is needed. Burden of secondary circuits can be measured and presented in VA.
Polarity testing
The currents phase displacement is shown, and the polarities of the outputs are clearly marked.
Heat runs
ODEN AT is ideal for performing heat runs. Current can be applied continuously or through programmable intervals. The times can be shown in minutes and hours which facilitates longterm testing capability.
Automatic reclosers and sectionalizers
ODEN AT can also be set to test circuit breakers with reclosing relays. Operating limits, partial times, total times and the number of operations before lockout can be measured. User-selectable reclosing sequences can be programmed for testing sectionalizers.
Testing integrity of ground grids and safety-ground devices
One way to test ground grids is by injecting current between a reference ground and the ground to be tested and measuring the voltage drop and the percentage of current flowing through the ground grid. The type X current unit included with ODEN AT is designed for this type of application. Personal safety grounds
must be tested at rated current, a task for which ODEN AT is well suited.
Features and Benefits
1.Display. The display presents time, output current, voltage, current shown on ammeter 2 and phase angle. You can scroll through entities Z, P, Q, R, X, S, power factor (cos φ) and I max.
2.Miniature circuit breaker used for current output. Interrupts output current. Can also be actuated manually for safe disconnection of load.
3.Current reduction button. Used during setting to reduce the output current to 1/30. Useful in order to avoid for example unintentional tripping and overheating.
4.Fine adjustment knob. Knob for fine adjustment of current and +/- buttons for coarse adjustment.

ODEN AT can also be set to generate pulse trains with user-se- lectable pulse and pause times.
11.Injection. Starts current injection and timing.
12.Momentary Injection. When this button is used, injection continues only as long as it is pressed. Useful in order to avoid for example overheating.
13.RS232 for computer. ODEN AT is equipped with a serial port for communication with PC (for transfer of test data for example).
14.Manual shut-off. Injection and timing are stopped when this button is pressed.
15.Automatic injection stop. Generation stops after a user-spec- ified interval or when condition at the input is met. The diodes show the selected OFF condition.
16.Stop-condition indicator. Indicates that a stop condition is met, voltage or contact triggered.
17.Status indicator. Indicates if a contact connected to the input is closed or if voltage is present.
18.Stop input. Used to freeze a reading or stop injection. Activated when current is interrupted by the object being tested, when an external contact is actuated or when a voltage is applied or removed.
