ARCO 400 Universal test set for recloser controls

Smart and rugged testing solution Coping with modern recloser functions Technology has significantly improved overhead distribution networks by reducing customer-minutes of interruptions through the use of modern reclosers. While the latest control technology brings advanced functionality, including distribution automation capabilities, testing all settings to ensure proper operation has become a challenge. What if controller testing can be done in only a few minutes? ARCO 400, the lightweight and easy to use test set, is the universal solution for all types of recloser controls. Connecting the...

for all types of recloser controls Simple plug-and-play functionality checks High testing flexibility ARCO 400 provides the fastest and easiest way to perform simple trip/close checks. Every smart controller adapter includes a chip through which ARCO 400 automatically recognizes the specific adapter and, once connected, configures itself for the test procedure. This allows immediate basic trip and close functionality checks via the controller's push buttons – without the use of any software. The accurate 3-phase 12.5 A current amplifiers enable both testing at very low amplitudes and the testing...

Designed to fit specific requirements Manual control and test templates Specific recloser and sectionalizer test modules in the ARCO Control software allow the convenient testing of any controller function. To meet your company’s test requirements, ARCO 400 also enables manual testing of the controller. These tests are performed through either the given test modules or by executing a test plan predefined in ReCoPlan, which saves time and reduces complexity during site testing. Distributed scheme testing Several ARCO 400s can be time-synchronized to GPS and controlled simultaneously with RelaySimTest....

Plug-and-play setup with OMICRON Smart Connect Safety first The interface on ARCO 400, extension cable, and smart controller adapter leading to the test set are safe to touch. This is possible due to a new connector concept where no blank pins are exposed on either side. Automatic detection by the ARCO Control software of a missing ground connection to the test set avoids potential dangers. Additionally the software indicates when live currents and voltages are being output. ARCO 400 Convenient and adaptable The ARCO Control software allows a quick start when executing injection tests. You can...

ARCO Control Easy testing of controllers ARCO Control, specifically designed for testing recloser and sectionalizer controls, is an easy to use software for ARCO 400. Commissioning and maintenance tests are easily performed through the software's comprehensive test tools. The software is configured to allow quick testing of recloser and sectionalizer controls in the field. The navigation menu guides you through each test sequence with step by step instructions. The test results are obtained quickly and reliably, and can then be exported for reporting purposes. ARCO Control runs on a Windows Laptop,...

Plug-and-play start up procedure Starting a new test is both easy and intuitive. Simply connect an ARCO 400 smart controller adapter and extension cable to ARCO 400 and the hardware will configure itself by reading the configuration associated with the smart adapter. After selecting the controller to be tested, the user has the option to input specific test data such as location, tester's name and report information. Tests can then be started right away by selecting the desired test tool. Plug in adapter The software recognizes the smart controller adapter once it is connected. Only the controller...

ARCO Control test examples Tripping Sequence test tool With this test tool, the functionality of recloser and sectionalizer controls is easily ascertained for full sequence, lockout, and automatic reclosing sequences. Sectionalizer testing simulates the trip-close sequence of an upstream device. The proper timing of the recloser or sectionalizer control is measured and included in the report. Application mode There are two different applications that can be tested with the Tripping Sequence test tool (recloser or sectionalizer). When selecting the DUT (device under test), the software also determines...

Trip Time Characteristics test tool The Trip Time Characteristics test tool checks both the operating characteristics of the recloser control and the switch logic between the fast and slow curve which occurs when a fuse-saving scheme is applied. For this, a complete test sequence is executed up to the lock out of the controller. To test the tripping behavior of a single curve only, repeated test shots can be sent to the controller in the Trip Only mode. The following parameters are set in this menu: > The optional time additions > The number of test shots on the fast curve > The current pickup...

Distributed Energy Resources (DER) are transforming modern power systems, and reliable antiislanding protection systems are essential for ensuring their seamless and secure integration. ARCO 400 enables tests for two-stage voltage and frequency protection functions, Rate of Change of Frequency (RoCoF), and Vector Shift. ARCO 400's guided workflow simplifies the testing process, helping ensure protection systems operate correctly and meet the grid code requirements. Voltage source Test Vector shift ~| The Voltage stage 2 and Frequency stage 2 modes use a pulse ramp method to test the stage protection...

RoCoF test tool The RoCoF test tool is designed to measure the rate of change of frequency without triggering other protection functions, such as voltage protection and vector shift protection. It offers flexible configurations that can be adapted to different testing scenarios, such as positive and negative frequency ramps. The Prefault time can be adjusted to ensure that the relay's RoCoF protection is in normal operation mode and ready to react to changes. The Start frequency can be set to a different value than the nominal frequency. Ramp Configuration The following parameters are set in...
