High-voltage receiving equipment and cogeneration facilities. This single unit supports various digital relay tests.
We have made it possible to conduct various tests related to high-voltage receiving equipment and cogeneration facilities, which were previously carried out by combining multiple models, in a single unit. This can be utilized for protection function tests in commercial facilities, office buildings, and factories. In addition to being compact and lightweight, the design takes actual work conditions into consideration, aiming to improve the workability at maintenance sites. 【Features】 ■ Voltage: 2 phases (up to 300V per phase), Current: 2 phases (up to 31A per phase) Diverse outputs from single-phase to three-phase three-wire (V connection), and unbalanced two-phase ■ Equipped with a microcurrent output range of 20mA (resolution 0.001mA) ■ Easy digital setting for high-accuracy amplitude, phase, and frequency output ■ Built-in counter allows for operation time measurement ■ Supports various protection relay tests Over/under voltage, over/under frequency, short-circuit direction, under power, reverse power, field loss, earth fault overvoltage, earth fault overcurrent, earth fault direction, overcurrent, ratio differential, phase loss/reverse phase ■ CB interlocking tests possible with two-phase current in series ■ Usable with generator sets (inverter type) and portable power supplies *For more details, please refer to the PDF document or feel free to contact us.
