Winding resistance test set with fast discharge for transformer maintenance. Ovento Systems carries the Megger MTO330 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. Stock is held in Plano, TX and normally despatches within one business day of order confirmation. Most enquiries on this model come from electrical testing contractors, utilities, substation service crews and motor repair shops. If you need several, or need them matched, say so on the request and we will quote as a set.

What is included with the MTO330

Every quote itemises exactly what is in the box. Accessories, adapters and carrying cases are priced individually, which matters if you are completing a kit you already part-own rather than buying from scratch. 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.
