2.1 DESCRIPTION

The PowerPad III Model 8336 is a 3-phase network analyzer with a color graphic display and built-in rechargeable
®
battery. This instrument can be used to:
● Measure the RMS values, powers, and perturbations on electric distribution networks
● Deliver a snapshot of the principal characteristics of a 3-phase network
● Track the variations of various parameters over time
The measurement accuracy of the instrument is better than 1% (not counting the accuracy due to the current sensors).
The instrument is also very flexible, with a choice of sensors allowing measurements ranging from a few milliamperes
(MN193) to several kiloamperes (AmpFlex
simple interface make it easy to use. The instrument is intended for technicians and engineers responsible for electrical
installation and network inspection and maintenance.

2.2 MEASUREMENTS

The Model 8336 principal measurements are:
■ The RMS values of AC voltages up to 1000V between terminals. By using ratios, the instrument can measure voltages
up to hundreds of gigavolts.
■ The RMS values of AC currents up to 10,000 amperes (neutral included). By using ratios, the instrument can measure
currents up to hundreds of kiloamperes.
■ The 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).
■ The frequency of 50Hz and 60Hz networks.
■ Current and voltage peak factors (neutral included).
■ Calculation of the harmonic loss factor (FHL), application to transformers in the presence of harmonic currents.
■ Calculation of the K factor (KF), application to transformers in the presence of harmonic currents.
■ Measurement of total harmonic distortion with respect to the fundamental (THD in %f) of the current and of the voltages
(excluding neutral).
■ Measurement of the 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).
■ Measurement of the RMS distortion value (d) for the current and the voltages (excluding neutral).
■ Short-term voltage flicker (PST) (excluding neutral).
■ Measurement of the long-term flicker of the voltages (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.
