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 done by combining multiple models, using 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 into consideration, aiming to improve operability at maintenance sites.
【Features】
■ Voltage: 2 phases (up to 300V per phase), Current: 2 phases (up to 31A per phase)
Diverse outputs including single-phase, three-phase 3-wire (V connection), and unbalanced two-phase.
■ Equipped with a microcurrent output range of 20mA (resolution 0.001mA).
■ High-accuracy amplitude, phase, and frequency output with easy digital settings.
■ Built-in counter for measuring operating time.
■ Supports various protection relay tests:
Over/under voltage, over/under frequency, short-circuit direction, under power, reverse power, field loss,
ground fault overvoltage, ground fault overcurrent, ground fault direction, overcurrent, ratio differential, phase loss/reverse phase.
■ CB interlocking tests possible with 2-phase current in series.
■ Usable with generator sets (inverter type) and portable power supplies.
