Solutions / Measurement & Analysis

Measured on site
with the HIOKI PQ3198-94

We install a HIOKI PQ3198-94, an IEC 61000-4-30 Class A power quality analyser, at your main incoming or critical feeders and record reactive power demand, harmonic spectrum, voltage events, flicker, power factor trend and load profile.

The campaign runs continuously on site and covers peak production, shift changes, weekend operation and idle periods. The dataset is used to find the cause of the power quality problem and to size the compensation system.

The measurement is a standalone paid service. If a Forte compensation system order follows, the fee is waived.

What We Measure

Five quantities recorded on all phases

Recorded simultaneously on 3 phases + N with the HIOKI PQ3198-94.

Harmonic Analysis (2nd–50th)

Individual harmonic measurement up to 50th order for both voltage and current. THD calculation, inter-harmonics, and K-factor for transformer loading assessment. Identify which loads are injecting distortion.

Reactive Power & Power Factor

Continuous cos φ and tan φ profiling across all load conditions. Displacement and true power factor (DPF & TPF). Capacitive/inductive reactive power demand by time of day, used for system sizing.

Voltage Quality Events

Detection and time-stamped logging of voltage sags, swells, interruptions and transients per IEC 61000-4-30. RMS variation tracking and event classification for root cause analysis.

Flicker Measurement

Short-term (Pst) and long-term (Plt) flicker severity measurement per IEC 61000-4-15. Critical for arc furnace environments and facilities near sensitive loads.

Load & Demand Profiling

Active (kW), reactive (kvar) and apparent power (kVA) profiling over the on-site campaign. Peak demand identification, load factor calculation and demand trend analysis for compensation sizing.

Our Process

Four steps: planning, installation, recording, report

1

Pre-Assessment & Planning

We review the facility's electrical topology, choose the measurement points (main incoming, critical feeders, problem loads) and set the campaign dates.

2

Equipment Installation

We install the HIOKI PQ3198-94 with flexible CT clamps at the chosen points. No shutdown is needed. Timestamps are GPS-synchronised.

3

Continuous Recording

Recording covers peak production, night shifts, weekends and idle periods. We check the data remotely during the campaign.

4

Analysis & Reporting

Forte analyses the harmonic spectrum, power factor trend, voltage events, flicker severity and load profile and compiles them into a report with a sizing recommendation and ROI estimate.

Deliverables
