Electrical Testing Equipment

Test and diagnostic instruments available for short and long term rental.

Overview

Electrical testing equipment from the Raptronics rental fleet covers relay and protection testing, primary and secondary injection, insulation resistance, contact resistance and circuit breaker analysis. The instruments are calibrated and available by the week or month.

Specialist test sets are expensive to buy and are often only needed a few times a year, around commissioning or a planned maintenance outage. Renting gives testing contractors, utilities and industrial maintenance teams the right instrument for the job without carrying it on their books for the rest of the year.

Every rental comes with support from our engineering team, who can help you pick the right instrument and get the most out of it on site.

Whether you are a testing contractor covering a peak in workload, a utility crew preparing for an outage season or an OEM running factory acceptance tests, we can put together a package of instruments for the duration of the job.

Types

  • Relay and protection test sets

    Secondary injection test sets for checking protection relays, their settings and the logic of the protection scheme.

  • Primary injection

    High current injection through the primary circuit to check CT ratios, polarity and the complete protection chain end to end.

  • Insulation resistance testers

    Testers for cables, motors, transformers and switchgear, used to check insulation condition before energization and during maintenance.

  • Contact resistance and breaker analysis

    Micro-ohm meters for joints and contacts, and circuit breaker analyzers for timing and motion, used during commissioning and breaker maintenance.

Applications

  • Commissioning

    Pre-energization testing of new substations, switchgear and protection schemes.

  • Maintenance outages

    Planned outages where a lot of testing has to be completed in a short window and extra instruments keep the crews moving.

  • Protection testing

    Routine and post-modification testing of protection relays and schemes.

Applicable standards

We carry the applicable standards for your voltage class. Please reach out with your inquiries for more details.

Availability and booking

Rental equipment is booked against your project dates. Demand peaks around spring and fall outage seasons, so booking early is the best way to secure the instruments you need.

Contact us with your test scope and dates and we will confirm availability.

Frequently asked questions

How long can I rent test equipment for?

Equipment is available for short and long term rental, by the week or by the month.

Can you help me choose the right instrument?

Yes. Tell us what you need to test and our engineering team will recommend the right instrument and support you during the rental.

What types of testing does the fleet cover?

Relay and protection testing, primary and secondary injection, insulation resistance, contact resistance and circuit breaker analysis.

Is rental suited to factory acceptance testing?

Yes. Rentals are used for commissioning, maintenance outages and factory acceptance testing.

Why rent test equipment instead of buying it?

Specialist test sets carry a high purchase price and need regular calibration, storage and maintenance. If an instrument is only needed for a few projects or outages each year, renting gives access to the right equipment when it is needed and removes those ownership costs for the rest of the year.
