Insulation Testers (5KV) Calibration
- Verifies that your 5 kV insulation tester measures insulation resistance accurately across its specified operating range.
- Readings are compared with traceable reference standards to confirm instrument performance.
- Supports reliable high-voltage insulation testing for electrical equipment, cables, maintenance, and compliance applications.
Insulation Testers (5KV) Calibration
5 kV Insulation Tester Calibration verifies that your instrument provides accurate insulation resistance measurements throughout its specified operating range. Reliable results are essential when assessing the condition of cables, motors, switchgear, transformers, and other electrical equipment. Our technicians use precision electrical standards and traceable reference equipment to confirm that your tester produces dependable readings at the required test levels.
During calibration, the insulation tester is assessed at several resistance points across its working range. Depending on the instrument and its available functions, the process may also include verification at a selection of high-voltage test outputs. These checks establish whether the tester is operating within the applicable performance limits and identify any significant deviation from the expected values.
Routine calibration helps reduce the risk of inaccurate insulation resistance readings affecting maintenance decisions, fault diagnosis, or electrical safety assessments. Regular verification supports reliable high-voltage insulation testing across industrial facilities, power systems, engineering workshops, utilities, and electrical maintenance environments.
Calibration certificates and documentation
Your equipment is returned in the same condition in which it was received and supplied with a due date sticker showing the next recommended calibration date. We also issue a calibration certificate and supporting calibration records, providing documented evidence of the measurements and checks completed to support inspection, maintenance, and compliance requirements.
