Megger MVCT VT and CT analyzer for substation instrument transformer testing

Megger MVCT Instrument Transformer Tester

Brand: Megger

SKU: 5016

The Megger MVCT is a lightweight, automated analyzer for testing current and voltage (instrument) transformers. It measures ratio, phase angle, winding resistance, burden, polarity and saturation — with knee-point voltages up to 30 kV using a DC technique — to IEC 61869 and IEEE C57.13, all from a portable 10 kg unit.

Description

The Megger MVCT is a portable CT and VT analyzer for protection and commissioning teams who need ratio, polarity, burden, and saturation checks in one light unit. It automates multi-ratio tap testing to IEEE C57.13 and IEC 61869 without hauling a heavy legacy set into the switchgear aisle.

Where UAE crews use the Megger MVCT CT/VT analyzer

On substation and industrial outages across the UAE, protection and commissioning engineers bring the Megger MVCT VT and CT Analyzer into the switchgear aisle to prove CT and VT ratio, polarity, and saturation before a bay goes back online. The unit stays under about 10 kg, so one person can run multi-ratio taps without dragging a heavy old-style test set through the yard.

What the Megger MVCT instrument transformer tester is for

The MVCT is a portable, automated analyzer for current transformers (CTs) and voltage transformers (VTs). It covers ratio, phase/polarity, winding resistance, burden, demagnetisation, and saturation — including knee-points up to about 30 kV via Megger’s DC technique — with automated routines aligned to IEEE C57.13 and IEC 61869.

What you get on site with the Megger MVCT

One instrument for both CT and VT testing
Multi-ratio CTs: saturation, ratio, resistance, and polarity across taps with far less lead swapping
CT ratio roughly 0.8–2,000 (extendable); VT ratio about 1–2,450
Built-in insulation check on many configs (500/1000 V DC, to ~20 GΩ)
Sunlight-readable colour touchscreen (or laptop/PowerDB / STVI depending on configuration)
Test CTs/VTs still mounted in transformers, breakers, or switchgear when fully isolated
