MagD Series

MagD Series

Step-Up Transformer

MagD is specially designed to cater the needs of testing of Instrument Transformers. Before new systems are put into service or after any occurrence of fault, Instrument Transformers need to be tested for their outputs. It is to be ensured that Instrument Transformers give proper outputs to protection relays.
  • Prepares excitation curves quickly and easily
  • Knee–point test of CTs
  • De-magnetise transformer cores
  • Conducts turns-ratio test of voltage transformers
  • Inbuilt voltmeter and ammeter
  • HV and LV outputs available separately
  • Online switching between HV and LV outputs
  • Visual Indicators for HV/LV output ON
  • Two-Hand operation enhances user safety
  • Interlocking feature for Variac Zero position for user safety
  • Thermal cut-off for instrument and user safety
  • Supplied with specially designed high voltage cables and rugged carrying case

EVSE-100

Multifunctional analyzer EVSE-100 is an instrument dedicated to diagnostics of electric vehicle charging stations and cables. Using a single device, we will perform a set of tests on these objects, ending with the generation of a professional report. Through appropriate simulation of CP and PP circuits, the meter can put the station into various operating states. This allows us to verify the correctness of the control system and perform measurements in the field of electric shock protection. We can complete the verification of functionality and safety by simulating errors on the power supply side, i.e. the charging station (ICCB), and charging side of the vehicle (CP circuit)
