Both single-phase and three-phase are available, In this research paper, automatic voltage stabilizer intends to three-phase unbalanced loads because most of the industries used in unbalanced load. Automatic voltage stabilizer consists of two units; measuring unit and regulating unit. In this automatic voltage stabilizer, variable autotransformer is used for the regulating unit and electronic control circuit is used for sensing unit. The main purpose of this research is the design and construction of servo control circuit In this paper, control circuit for automatic voltage stabilizer provides voltage comparators, relays, presets and servomotor that compare Instantaneous input and output voltage. This value can be adjusted in the electronic control circuit until the desired voltage is reached, At that time, the output of measuring unit is zero. Servo motor is attached to rotate the brush arm of the variable autotransformer until the output voltage is stable. The electronic control circuit will operate within the fluctuation range from 130 V to 250 V and 21 kVA (single-phase) is designed. The output sensitivity is ±1%. Its frequency range is 50 Hz. The feature of this stabilize r is the input wave form equal to the output wave form. As a phase loss sensing, phase sensing bridges are used. If the input voltage is lower than 130 V or higher than 250 V, the system will be automatic shutdown."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "voltage comparators"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Design and construction of 20 k VA automatic voltage stabilizer control system.pdf", "filesize": [{"value": "3511 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3511000.0, "url": {"url": "https://meral.edu.mm/record/2643/files/Design and construction of 20 k VA automatic voltage stabilizer control system.pdf"}, "version_id": "5c14c5bc-f87b-4414-916b-81084951c634"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Proceedings of the First International Conference on Science and Engineering", "subitem_volume": "1"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Su Hlaing Myint"}, {"subitem_authors_fullname": "Salai Tluang Za Thang"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2009"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://uyr.uy.edu.mm/handle/123456789/357"}, "item_title": "Design and Construction of 20 kVA Automatic Voltage Stabilizer Control System", "item_type_id": "21", "owner": "1", "path": ["1582967549708"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002643", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2643", "relation": {}, "relation_version_is_last": true, "title": ["Design and Construction of 20 kVA Automatic Voltage Stabilizer Control System"], "weko_shared_id": -1}
