MILLI VOLT DROP TEST SET

This is a portable DC Injection Set suitable to observe millivolt drop across low resistance elements, contacts, switches, D.C. motor commutator segments etc.

Input : 230 volts, 50Hz, 1Phase, AC upto 300A.
400/415 V, three phase, 4 wire, 50Hz. , AC above 300A.
Output : Continuously variable from zero to maximum rated current required.

Series: MVDTXPYYU;
X denotes single phase input (1) or three phase input (3);
YY denotes DR or OC i.e. either the transformer will be air-cooled or oil cooled type.
U denotes no. of units ? either one (1) or two (2).

Type: Y1Y1Y1AZZV;
Y1Y1Y1 denotes the maximum current capacity in Amp.
While, for Y1KAZZV; Y1 denotes the maximum current capacity in kAmp.
ZZ denotes the open circuit voltage rating.
We manufacture these sets in wide range up to 3KA and of various

capacities.

Duty Cycle : 5 minutes ON & 10 mins. OFF. Sets of other duty cycle can also be manufactured at extra cost.
Units : 1 unit upto 500A.
2 units above 500A upto 3000A.

Transformer : Air-cooled upto 1000A. Oil cooled above 1000A upto 3000A.

Step down rectifier transformer with full wave rectifier bank consists of 4 nos. silicon diodes along with surge suppressor.

Protection against overload & short circuit is provided. ?Zero Start Interlock? protection is also incorporated.

Metering: Analog millivoltmeter, voltmeter & shunt operated ammeter. Digital meters can be provided at extra cost.

One set of probes to measure millivolt drop between two points of test sample is provided.
