Recorders / Analyzers
Power Quality Test Equipment

This modern power network analyzer using leading edge DSP technologies, allows recording tasks, acquisition and analysis of dozens of electrical magnitudes simultaneously and in only one measurement cycle.

With 8 analog channels for voltage and current, or alternatively 8 voltage channels (the same instrument), all magnitudes are simultaneously measured, without any limits, in AC and DC.

The Topas 1000 can measure: For each individual phase and three phase:

Topas 1000
• V RMS Instant / Average / Min / Max.
• A RMS Instant / Average / Min / Max.
• W Instant / Average / Min / Max.
• VAR Instant / Average / Min / Max.
• VAR Delta Mean
• VA Instant / Mean
• Power Factor Instant / Mean
• kWh , KVARH, KVAH
• Demand for W, VA, Power Factor Instant / Max.
• Voltage unbalance
• KWHi
• VARHi
• Frequency
• THD
• Harmonics 0 to 50, for current and voltage and also power with angle and mode.

• Interharmonics

• Phasors: All measurements according to IEC 1000-4-7
(now 61000-4-7) standards as specified by ENRE.

• FLICKER measurements are performed automatically, and the analyzer calculates the short and long duration severity indexes (Pst and Plt), according to IEC 61000 (ex IEC 868) standards annex 1
Transient analysis on all voltage and current channels
Sampling rate: 10 kHz (10 MHz optional)
Trigger type: by RMS levels, Peak, Disturbance, Derivative, excess THD level or individual harmonics, etc.
