Best service for maximum safety

A maintenance inspection is mandatory every 6 years at the latest.

Maintenance inspections for voltage detectors according to IEC 61243-1 and phase comparators according to EN 61481 are mandatory in Germany according to DGUV V3 – accident prevention regulation for electrical systems and equipment. After a maximum of 6 years, these devices must undergo a maintenance inspection. Requirements in other countries may differ.

Some of the test components

• Visual and dimensional check
• Testing of the self-test device
• Leakage current test
• Protection against bridging and spark resistance
• Measurement and documentation of the threshold voltage

Depending on the frequency of use and stress, shorter inspection intervals may also be necessary. This applies to devices:

• that are used intensively
• frequently in use
• subject to heavy strain
• show signs of wear

PFISTERER recommends carrying out a risk assessment in order to evaluate the required test cycle as well as for legal protection.

PFISTERER recommends maintenance inspections every 5 years outdoors and every 10 years indoors

Earthing and short-circuiting devices must generally be checked for proper condition before use. Make sure that the insulation is in perfect condition, has no discolouration and that the conductor cable is not bare at any point. For earthing and phase terminals, the clips should be easy to open and should not be misaligned. Any rust spots must be removed. If necessary, country-specific requirements must be observed.

PFISTERER recommends a comprehensive maintenance inspection every 5 years for devices used outdoors and after 10 years for devices used indoors. In case of doubt and after just one short circuit, the earthing and short-circuit device must be excluded from reuse. It can only be re-released after a maintenance inspection.

Test components

• Visual and functional test
• Measurement and documentation of contact resistances

PFISTERER recommends maintenance inspections every 6 years

Earthing and operating poles must generally be checked "visually" for externally visible damage before each use. PFISTERER also recommends a haptic test of the surface quality. In case of irregularities, refrain from using it. The pole must be replaced at the latest when loose glass fibre components are detected.

DIN VDE V 0681-1 recommends a maintenance inspection for operating poles every 6 years. If necessary, country-specific requirements must be observed.

Test components:

• Visual and functional test
• Measurement and documentation of the leakage current

The PFISTERER reminder service (SP and SPPC only) provides a timely reminder of the upcoming maintenance inspection. Registration is required for this.

Needless to say, you can also contact us directly when the maintenance inspection is due.

Send us your voltage detector with your shipping provider.

Our experts clean your device and carry out the standard-compliant visual and technical inspection.

If a technical fault or a safety-relevant defect is detected during the maintenance inspection, we will contact you and discuss the further course of action together.

We will then return your device to you in a professional manner, including an inspection report and a new inspection sticker.

Normally, you will receive your device back within 14 days from the date of dispatch.
