1. Strict Pre-Test Safety & Site Preparation
Prioritize operational safety by fully cutting off the power of all electrical equipment and circuits under test. Thoroughly clean dust, moisture and corrosive residues from the test surface to eliminate external interference. Meanwhile, inspect the test leads and probes for breakage or aging to ensure intact device performance before testing.
2. Match Correct Test Voltage for Scenarios
Peakmeter insulation tester supports multiple professional voltage gears. Select the corresponding test voltage strictly based on the specification of tested objects, such as low-voltage cables, motors and electrical appliances. Matching voltage settings ensure accurate, standard-compliant resistance data and avoid invalid test results caused by improper gear selection.
3. Standardize Probe Connection & Operation
Firmly attach the two test probes to the target test terminals of the equipment. Keep the connection tight and stable without loose contact. Avoid touching the metal part of probes during the whole test process, which not only ensures stable signal transmission but also effectively guarantees personal operational safety.
1. Early Detection of Hidden Insulation Defects to Eliminate Shock & Fire Hazards
Peakmeter insulation testers apply multi-grade DC test voltages (50V–5000V) to quantify insulation resistance of cables, motor windings, transformers and solar equipment, accurately capturing subtle degradation signals caused by aging, moisture, chemical corrosion and physical cracks long before visible faults emerge. Unlike visual inspection that misses internal insulation damage, the device automatically calculates DAR and PI values to judge damp or contaminated insulation, flagging excessive leakage current risks that would otherwise trigger fatal electric shock to on-site staff or arc-induced electrical fires in power distribution rooms, factories and photovoltaic stations. With real-time high-resolution digital & analog dual display, technicians instantly spot abnormal low resistance readings and locate faulty segments, cutting off potential safety accidents at the source rather than dealing with catastrophic aftermaths.
2. Strict Compliance with Global Electrical Safety Standards to Standardize Mandatory Maintenance Testing
All Peakmeter insulation resistance testers are manufactured to meet EN61010-1, EN61557-1 and CAT III 1000V / CAT IV 600V safety ratings, fully matching IEC 60364 and IEEE 43 mandatory periodic insulation testing requirements for new equipment acceptance, post-repair verification and regular facility maintenance. Industrial parks, construction sites and power plants face legal liabilities if they skip standardized insulation tests; Peakmeter’s built-in data storage, comparison judgment and timer recording functions generate traceable test records that pass official safety audits and inspection checks seamlessly. Its anti-overvoltage protection, automatic capacitive discharge and insulated alligator clip probes eliminate secondary hazards during testing, ensuring every routine inspection fully adheres to global electrical safety codes without compromising operator protection.
3. Prevent Unplanned Equipment Breakdown & Costly Safety Accidents via Predictive Maintenance
Undetected insulation failure leads to sudden motor burnout, cable short circuits and full production line shutdowns, accompanied by costly fire repair fees, equipment replacement losses and workplace injury compensation claims far exceeding the investment in regular Peakmeter testing. By integrating temperature compensation, wide measurement range up to 5TΩ and MAX/MIN/AVG data analysis, Peakmeter testers enable predictive maintenance: maintenance teams arrange targeted insulation repair or replacement during planned downtime instead of facing emergency halts triggered by sudden insulation breakdown. For renewable energy projects, marine electrical systems and heavy manufacturing workshops with harsh humid/dusty environments, periodic Peakmeter insulation checks extend equipment service life, stabilize power system operation and greatly reduce the probability of safety incidents that threaten personnel lives and corporate property assets.
