About This Product
■Summary
A variety of tests for high-voltage power receiving equipment and cogeneration facilities, which previously required a combination of multiple relay testers, can now be performed using a single unit. It can be used for protection function tests in commercial facilities, office buildings, factories, etc. In addition to being compact and lightweight, the design takes actual work into consideration, in pursuit of improved workability at maintenance sites.
Main features
■Voltage 2-phase (maximum 300V per phase), current 2-phase (maximum 31A per phase) output
・Various outputs from single-phase to three-phase three-wire (V connection), two-phase unbalanced, etc.
・Equipped with minute current output of 20mA range (resolution 001mA)
・Easy digital settings for highly accurate amplitude, phase, and frequency output
・Built-in counter allows measurement of operating time
・Supports various protection relay tests
・Over/under voltage, over/under frequency, short circuit direction, insufficient power, reverse power, loss of field, earth fault over voltage, earth fault over current, earth fault direction, over current, ratio differential, open phase/out phase
・CB interlocking test possible by 2-phase current series
・Can also be used with a power generator (inverter type) or portable power source
Light and compact, easy to transport and install
■Weight 16kg, width 400mm x depth 250mm
・The functions and performance required for protection relay testing of power receiving equipment, which was conventionally performed using a combination of multiple models, have been combined into one compact housing.
・The size is 400mm wide x 250mm deep x 350mm high, and weighs 16kg, so it can be carried by one person.
Abundant testing functions condensed into one device
■Covering high voltage power receiving equipment and cogeneration related tests
- Testing of various protection relays is possible with this one device.
・The work required to transport and wire multiple dedicated test instruments can be reduced.
-Equipped with an auxiliary power output, it is also possible to drive the protective relay that is the subject of the test.
Easy test setup and collection of test results
■Equipped with main body memory and USB memory interface
- Save settings and measurement results to the main unit by simply pressing the dedicated key.
・Automatic saving is also possible by setting in advance.
- Up to 256 data can be saved for up to 99 tests.
- You can streamline the process of recording test results. In addition, data from the main unit can be exported to USB memory, so you can smoothly create a report after the test.
■Terminals and operation parts are consolidated on the operation panel
All wiring and test equipment operations can be performed on the operation panel.
