HIOKI PW3360-20/500 Clamp-On Power Logger Kit – 500A 3-Phase Energy Auditing & Compliance Documentation
Electrical contractors, maintenance teams, and facility managers across New Zealand face a critical challenge: proving electrical system performance and energy efficiency without disrupting operations. Traditional handheld meters give you a snapshot—but what happens over time? How do you document power demand patterns for an entire site?
How do you prove that solar installations are performing to specification, or that industrial equipment is running efficiently? Without documented evidence, you’re left guessing about power quality, demand spikes, and energy waste. You need continuous, site-wide monitoring that creates audit trails for compliance, diagnosis, and optimization—without requiring dedicated IT infrastructure or constant manual readings.
SOLUTION OVERVIEW
The HIOKI PW3360-20/500 Kit delivers continuous, automated power monitoring that transforms how you approach energy audits, compliance documentation, and system diagnostics. Instead of snapshot readings, you capture detailed power data across hours, days, or weeks—stored directly on SD cards for later analysis and reporting. The integrated 500 A clamp sensors eliminate the need for separate equipment orders; everything you need is included and ready for deployment on New Zealand electrical systems.
This compact 550 g logger fits into confined plant rooms and ceiling cavities, making it practical for real-world job sites where access is limited. The QUICK SET feature walks you through 3-phase connections step-by-step, preventing the wiring mistakes that compromise data accuracy. HIOKI’s robust design handles typical New Zealand site conditions—industrial vibration, temperature fluctuations, and high-use environments—while maintaining ±0.3% measurement accuracy.
Whether you’re proving solar system performance under AS/NZS 5033, documenting industrial energy baseline for efficiency programs, or verifying power factor compliance across facility circuits, the PW3360-20/500 provides defensible, traceable evidence.
KEY BENEFITS & FEATURES
- Continuous Multi-Phase Monitoring That Captures Real Patterns Unlike spot checks, the PW3360-20/500 logs voltage, current, power, and demand simultaneously across three channels. You see actual consumption patterns, not averages. For solar installers verifying system integration into grid-connected properties, this means documenting instantaneous power injection and demand interaction—critical data under AS/NZS 5033. For facility managers, it reveals demand peaks that inform capacity planning and efficiency opportunities.
- 500 A Clamp Sensors—Everything Included, No Separate Orders The kit includes full-capacity 9661 clamp sensors up to 500 A, eliminating the frustration of incomplete equipment and unexpected costs. You mount the logger once, then monitor multiple circuits or phases without repositioning the base unit. The multicolored clips and spiral tubes keep everything organised on site, reducing setup time and improving measurement accuracy.
- 3-Phase Capability for Real New Zealand Industrial Sites Single-phase equipment matters, but most New Zealand industrial and commercial properties run 3-phase circuits. This logger simultaneously captures all three phases, giving you complete system visibility. No guesswork. No jumping between measurements. Complete load distribution data in one session.
- Data Logging That Creates Compliance Audit Trails Store months of raw data on the included 2 GB SD card. Access real-time and historical graphs on the 3.5″ color display, or transfer data to your computer via USB/LAN for professional reporting and analysis. The GENNECT One SF4000 software (included) transforms raw data into graphs and reports suitable for compliance documentation, client handover, and internal analysis.
- Engineered for New Zealand Field Conditions At just 550 g, it’s portable enough to carry between job sites yet robust enough for harsh industrial environments. The compact design (180 mm × 100 mm × 48 mm) fits into spaces where bigger equipment can’t reach—crucial in retrofit projects and confined plant rooms. Battery operation (6 hours continuous) or AC power gives you flexibility on sites with variable power availability.
- Wiring Check & QUICK SET—Eliminates Setup Errors Three-phase connections are straightforward once you understand the logic, but mistakes happen. HIOKI’s on-screen QUICK SET guides you through connections, and the wiring check function flags errors before measurement begins. This small feature has prevented countless days of wasted effort from corrupted data.
APPLICATIONS & USE CASES
Solar Installation Performance Verification (AS/NZS 5033 Compliance) Installers must document system performance and grid interaction. The PW3360-20/500 logs real-time power injection, voltage stability, and phase balance over days or weeks—providing the evidence of compliant operation required by standards and insurance. Compare baseline grid consumption against post-installation data to prove system contribution and customer benefit.
Industrial Energy Audits & Efficiency Programs Facility managers identify where energy is wasted—often in demand peaks and power factor issues. This logger captures demand profiles across all phases over extended periods, revealing patterns that spot checks miss. Armed with actual data, you negotiate better supply contracts, justify equipment upgrades, or prove energy savings post-efficiency intervention.
Power Quality Investigation on Critical Circuits When equipment fails prematurely or behaves erratically, power quality often plays a hidden role. Log voltage stability, frequency variation, and harmonic content (with PW3360-21 option) to diagnose whether site conditions are contributing to failures. This data supports warranty claims and informs maintenance strategies.
Load Distribution & Electrical Compliance Testing Commercial buildings must prove balanced load across phases under AS/NZS 3000. The simultaneous 3-phase logging shows actual distribution and identifies circuits contributing to imbalance, enabling remedial rewiring or load rebalancing documentation.
Preventive Maintenance & Baseline Establishment Before critical equipment fails, establish a power consumption baseline. Regular logging detects gradual changes—a sign of motor degradation, bearing wear, or control system drift—allowing planned maintenance before failure.
