Hioki PW8001-01 - Y-Δ Conversion

Delta Conversion Function
Y–
Δ
conversion
This function can be enabled in 3P4W wiring mode.
This can measure line voltages when phase voltages are inputted from a Y-connected circuit.
The voltage waveforms, various measured voltage values, and harmonic voltages are all inputted
as phase voltages; however, they are calculated as line voltages.

• The vector diagram shown on the wiring screen is the same as the 3P3W3M vector diagram.
• Peak-over judgment and the voltage peak value display range are determined using not-
converted values.
• When the voltage range is set to auto-ranging, voltage range switching is determined using
converted measured values.
