 NMC DC Shunts are used with accessories to  measure DC Current. It produce millivolt drop  against  its terminals when current is passed  through shunt.  Available with current ratings from  5A to 10,000A  and 60mV, 75mV or 150 mV drop.  Shunts are built  according to their current  capacity.
 Accuracy : ± 1% as per ISS 1248/84 Ammeters  above  30 Amps are to be used with external  shunts.



CURRENT TRANSFORMERS

The basic application of current transformers are :  
  • Lowering the very high primary current passing through bus bars, cables, or wires to 5A or 1A. A measurable quantity by measuring instruments.

  • Isolating the measuring instrument and protective devices from mains.

  • Reproduces proportionate primary current on its secondary side required for extending the range of the instruments.

EARTH TESTER


INTRODUCTION

Electronic Digital Earth Resistance Tester is direct replacement of the conventional hand generator type tester. It is designed for measurement of the resistance of earthing used in the electrical equipment as well as for measurement of ground resistivity. It can be used for measurements of the other low regular and liquid resistances. It can also be used for measurement of voltage AC, voltage DC and resistance. This instrument finds wide application for testing earthing installation in power based industries,
telecommunication networks and electrical traction systems etc.

INSULATION TESTERS


Models


DIT-914

- Four voltages (500V, 1KV, 2.5KV and 5KV)
- Auto-ranging and menu-driven
- A bar-graph which displays the voltage decay during the discharge of the tested circuit and the voltage stressing the insulation while the test is in progress.
- A timer which shows the elapsed time when the test was
"ON" and also shows the total time of the test.
- Displays a voltage warning and sound when AC or DC is present before injecting the test voltage.
- A buzz will intermittently sound when high voltage is
generated and continues until the circuit is fully discharged.
