Megger Relay Test Set Repair & Calibration

Status: Both the current SMRT and FREJA sets and the older SVERKER, MPRT, ODEN and PCITS families that protection crews still use are on our repair and calibration list.

A relay test set proves that protection will trip when it should, so its own outputs have to be right. SMRT, FREJA and SVERKER sets push sustained current through their amplifiers during commissioning work, and the ODEN and PCITS primary injection sets run hundreds of amps, which is hard on output stages, fans and contacts. We repair Megger protection test equipment at the component level and recalibrate every channel before it returns to the substation.

Common Megger Relay Test Set Problems We Fix

  • Output channel dead or low — power amplifier output stage failure from sustained high-current testing
  • Voltage or current output off — source calibration drift
  • Won’t connect to PC or the substation network — USB, Ethernet, or GPIB interface failure
  • Display or STVI controller touchscreen unresponsive
  • Overheats during long test sessions — cooling fan bearing wear
  • Timing/sync errors — GPS timing module failure
  • Channels intermittent — internal switching matrix contact wear

What Calibration Covers on a Megger Relay Test Set

When a relay fails a test, you need to know the fault is in the relay and not the test set. Calibration on these sets checks:

  • Voltage and current amplitude on each output channel
  • Phase angle between channels
  • Frequency of the generated outputs
  • Timer and binary input response, which every trip-time result depends on
  • Output current on the ODEN and PCITS primary injection sets

Measured results are documented on a NIST-traceable certificate.

Sending Us a Megger Relay Test Set

  1. Write to us. Email us or open a service request with the model number and the problem.
  2. Ship it in. Sets come to us from all over the US, and a prepaid label is available on request.
  3. Give the go-ahead. We diagnose it, send a firm and no-obligation quote, and start the repair only after you approve.

Email: info@junecompany.com | We back every relay test set repair with a 90-day parts-and-labor warranty, and each set returns with NIST-traceable calibration.

Frequently Asked Questions

How much does Megger relay test set repair cost?

We start with a flat evaluation fee, which is credited toward the repair. Once we know what failed, you get a firm price for the set and decide from there.

How long does the repair take?

Most relay test sets are back on the road 1 to 5 business days after they arrive, with expedited service available. High-current amplifier rebuilds on the SMRT and ODEN may run longer, and we say so in the quote.

One of my output channels is dead or weak. Can you fix it?

Yes. Power amplifier output-stage failure from sustained high-current testing is the most common fault on these sets, and we fix it by replacing the failed parts on the amplifier, then test the channel against our standards until it meets its rated voltage and current.

My voltage or current output is off. Can you recalibrate it?

Yes. Source calibration drift is repairable and recalibrated, and the set comes back with a NIST-traceable certificate documenting measured output accuracy.

My STVI controller or onboard touchscreen isn’t responding. Can you repair it?

Yes. STVI handheld and onboard display failures are common on field-used sets and fully repairable, restored so you can run manual and automated test plans again.

Won’t communicate with my PC or the substation network. Is that repairable?

Yes. USB, Ethernet, and GPIB interface faults that stop the set from talking to your software or the IEC 61850 network are a routine repair, restored for reliable connection and control.

My relay test set isn’t in the table. Can you repair it?

Probably. The table covers the common SMRT, FREJA, SVERKER, MPRT, ODEN, PCITS and STVI models, and we see other Megger protection test gear too, so choose the closest entry or email us. Crews commissioning a substation tend to check insulation on the same visit, so we also provide Megger insulation tester repair.

Who uses Megger relay test sets?

Substation protection engineers, relay-testing contractors, utility protection departments, power-generation facilities, and industrial plant electrical-maintenance teams rely on the SMRT, FREJA, and SVERKER systems to test electromechanical, solid-state, and microprocessor protective relays during commissioning and maintenance. For full manufacturer details, see Megger’s protection relay testing page.
