MagD

SCOPE proudly introduces Step-Up Transformer - MagD, specially designed to cater the needs of testing of instrument Transformers. Before new systems are put into service or after any occurrence of fault, the instrument transformers need to be tested for their outputs. It is to be ensured that these instrument transformers are giving proper outputs to the protective relays.

MagD is used to plot excitation curves for instrument transformers. Inbuilt voltmeter and ammeter, eliminates the need of external meters for plotting of curves. It can also be used for de-magnetization of transformer cores and also turns-ratio tests can be conducted using MagD.

Thermal cutoff , Two-hand control and Variac Zero interlock is deployed for user safety and protection.

Features

  • Prepare excitation curves quickly and easily
  • Knee – point test of CTs
  • De-magnetize transformer cores
  • Conduct turns-ratio test of voltage transformers
  • Inbuilt voltmeter and ammeter eliminates the need of external meters
  • HV and LV outputs available separately
  • Online switching between HV and LV outputs
  • Visual Indicators for HV/LV output ON
  • Two-Hand control enhances user safety
  • Interlocking feature for Variac Zero position for user safety
  • Thermal cutoff for instrument and user safety
  • Supplied with specially designed High voltage cables and rugged carrying case
