“JMD” milli volt drop test set model MVDTS-0-100/ 200…..3000 Amp is capable to measure milli volts between 1mA to 2000mA. The instrument can provide test current between 0-100/200 ........3000Amp subject to the capacity chosen, load resistance and supply voltage. the system uses four terminal method –two for current supply and two for measurement. The unit has high current capability and is of compact design suitable for testing high current contacts of circuit breakers, switches, bus-bar joints and other application where high current junctions exist. The unit is housed in M.S. sheet /aluminum housing, light in weight and supplied with 2nos.current leads with clamps and 2 nos. potential leads with clips.
• Compact size for portability.
• Easy to operate and operation manual is provided.
• Built in safety arrangement for operate and equipment.

“JMD” motorised oil test set is suitable for testing dielectric strength of insulating oils. E.g. Transformer oil etc confirming to is: 335 for carrying out test as laid down in is:6792. The unit consists of high voltage transformer with epoxy encapsulated secondary coils. The high voltage transformer feeds H.T through electrodes to the oil under test in a removable oil test cup with adjustable gap as per is specifications. The H.T is varied steplessly by varying the primary voltage through ON/OFF switch push buttons, indicators, switch, contractor and electrical interlock etc. are in-built in the unit. The complete unit is housed in a Powder coated sheet metal housing. Inspection window or transparent cover is provided to inspect the breakdown of oil.
