Three-phase active power meter, three-phase non-active power meter specifications:
Note 1: This instrument uses an integrated time-division multiplier for measuring active and reactive power under three-phase balanced or unbalanced loads; the instrument operates at a frequency of 50Hz. If a current with an operating frequency of 60Hz is required, please specify this in the contract.
Note 2: The zero position of the reactive power indicator of this instrument is at the 12 o'clock position on the dial. The left side is the leading capacitive reactive power and the right side is the lagging inductive reactive power.
Note 3: Three-phase active and reactive power meters can be configured with a negative power scale of 10-20% as required; or a red line can be drawn at the set value as needed.
Note 4: The Type 72 three-phase active and reactive power meter has two structures: integrated (meter head and converter are integrated) and separate structure with additional device (meter head does not have converter, additional device contains converter). Please specify if necessary.
