Automatic three-phase turns ratio tester covering all common vector groups. Ovento Systems carries the Megger TTR300 as used and refurbished stock within our power system & substation testing range, sourced through equipment liquidations, service company fleet upgrades and OEM trade-ins across North America and Asia.

Output current, timing and measurement channels are exercised against a reference load, and supplied cable sets, clamps and software keys are itemised individually. Everything is tested before it is listed and ships from our Plano, TX facility, usually same day. We supply this model most often to electrical testing contractors, utilities, substation service crews and motor repair shops. Tell us the quantity and the delivery date you are working to and we will confirm both.

What is included with the TTR300

The instrument itself, its standard supplied leads or probes where noted, and a written condition report. Cases, modules and calibration certificates are quoted separately so you only pay for what you actually need. If you are completing an existing kit, tell us the part numbers you are missing and we will check accessory stock against them.

Buying this class of instrument used? 5 kV, 10 kV or 15 kV: choosing an insulation tester covers what to check before you pay.
