2.1. FUNCTIONS
The Model 8436 a three-phase network analyzer with color graphic display and built-in rechargeable battery. The instrument:
■
measures RMS values, powers, and perturbations of electric distribution networks
■
delivers a snapshot of the principal characteristics of a three-phase network
■
tracks variations of various parameters over time
■
provides IP67 (watertight) operation
The measurement uncertainty of the Model 8436 is better than 1% (excluding uncertainties due to connected sensors). The instrument
is also versatile, with a choice of sensors providing measurements ranging from a few mA (MN193) to several kA (AmpFlex
The instrument is compact and impact resistant, with a simple and easy-to-use interface. It is designed for technicians and engineers
performing electrical network installation, inspection and maintenance.
2.1.1. MEASUREMENTS
The Model 8436 measures:
■
RMS values of AC voltages up to 1000V between terminals. By using the ratios, the instrument can measure voltages up to
hundreds of gigavolts.
■
RMS values of AC currents up to 10,000A (neutral included). By using the ratios, the instrument can measure currents up to
hundreds of kiloamperes.
■
DC components of voltages and currents (neutral included).
■
Minimum and maximum half-cycle RMS voltage and current values (excluding neutral).
■
Peak voltage and current values (neutral included).
■
Frequency of 50Hz and 60Hz networks.
■
Current and voltage peak factors (neutral included).
■
Harmonic loss factor (FHL), application to transformers in the presence of harmonic currents.
■
K factor (FK), application to transformers in the presence of harmonic currents.
■
Total harmonic distortion with respect to the fundamental (THD in %f) of the current and of the voltages (excluding neutral).
■
Total harmonic distortion with respect to the RMS AC value (THD in %r) for the current and the voltages (neutral included).
■
Active, reactive (capacitive and inductive), non-active, distortion, and apparent power, by phase and cumulative (excluding
neutral).
■
Power factor (PF) and displacement factor (DPF) or cos Φ (excluding neutral).
■
RMS distortion value (d) for the current and the voltages (excluding neutral).
■
Short-term voltage flicker (PST) (excluding neutral).
■
Long-term voltage flicker (PLT) (excluding neutral).
■
Active, reactive (capacitive and inductive), non-active, distortion, and apparent energy (excluding neutral).
■
Current and voltage harmonics (excluding neutral) up to order 50: RMS value, percentage referred to the fundamental, (%f)
(excluding neutral), or the total RMS value (%r), minimum and maximum and sequence harmonics.
■
Apparent harmonic power up to order 50 (excluding neutral): percentages referred to the fundamental apparent power (%f) or
the total apparent power (%r), minimum and maximum of a rank.
■
Inrush currents, starting of motors.
