"Delta" H.V. Flash Tester are made heavy duty, keeping in mind long term reliability. Rating are 0 - 5 kV @ 100 mA. Trip current settings can be provided as 25 mA - 50 mA - 75 mA - 100 mA OR 10 mA - 25 mA - 50mA- 75 mA. As an option, a timer can be provided to test an object for a preset time. Most of the capacitors used in the lighting industry are hand made, esp. the metallization of electrodes . The qualitiy of these capacitors change from batch to batch." Delta" has developed a test panel with high discharge currents (up to 10 kA pulse) to test the capacitors samples cyclically for a specified duration. If during this test, any capacitor short-circuits; a lamp- inside the panel will light up. After the test capacitors have to be tested for their impedance by passing the current at rated voltage This is a destructive test; all the capacitors tested on this panel have to be destroyed afterwards & not to be used.

  " Delta" makes Earthing Compliance Test Panel for various appliances. This panel has high output impedance, adjustable current source 0 -30.0 A @ 6 V max. By measuring the mV-drop between earthing terminal of the plug & accessible metal part of the appliance body , earthing resistance has to be measured. Current to be passed depends on the standards specified for that appliance & the resistance has to be less than specified milliohms.

"DELTA" Control Engg.Corp. have introduced Digital Test Panel for checking electrical performance of lighting ballasts/ fixtures, single phase motors, appliances and hand tools etc. The Panel is designed to handle p.f. range from 0.04(lag) to unity. The self-contained Panel obviates the need for one to fabricate his own test panel using umpteen different types of analog / digital instruments. The composite V-A-W Meter is Delta"s own innovation and the wattmeter can handle wide range of voltage, current, and p.f. The Panel can test either ballasts alone for production QC or completed fixtures or any kind of motive / heating loads upto 8 Amp. The equipment is built in simple and rugged fashion; it can withstand momentory motor starting currents (up to 20A) without any damage.

delta digital ohmmeter mode dmz-4 is designed keeping in mind the requirements of electrical equipment manufacturers. High accuracy and repeatability of results is achieved by precision constant current injection into object under test. This ohmmeter is laboratory grade instrument, the performance of which cannot be matched by the most of commercial digital instrument.

Introduction of composite V-A-W Meters by "Delta" in 1989 has been a runaway success;their large number in the field all over the Country bears testimony to their performance and reliability. "DELTA" have also been the pioneers of the Digital Wattmeters in the Country since 1982. Those electrical engineering industries which comply with BIS standards, they will find Composite V-A-W meters as a necessity. The concept composite not only dose away with interconnecting wiring, it also saves space in the panel and is economical too.Applications are in:· Domestic Appliances Manufacture, such as fans, mixes, hotplates.· Lighting Equipment Manufacture.· F.P.H. Motor Industry· Industrial Heater Manufacture.When used PC/ CT signals, composite V-A-W meters are useful for utilies as well. SPECIFICATIONS: DIMENSIONS: 290mmW x 180mmDAUX. SUPPLT: 200-250 VAC @ 8 VAFREQ. RESPONSE: 10Hz- 10kHz (all displays)CONNECTIONS: 1) Aux. supply by barrier terminals on the rear2) Load supply/ load terminal of 4 mm ø - 15A rating on the front dial (rear connections only against specific request.)a) True-RMS version of DT-200 (SP) is DTRMS-200, having the same specifications except the voltage & the current displays are of true- RMS type. All of the Delta's digital wattmeter are of true - RMS type. DTRMS -200 is very useful for measuring distorted current waveforms especially in electronic ballasts.b) When using DT-2000/ DT-2000 (SP), if frequent heavy starting surge currents are encountered, the use of external CT operated models, for more reliable operations, is suggested.c) For custom-built models send with your specific requirements. PROTECTION: 1) The aux. supply to the instrument is protected by a metal-oxide varistor against high voltage surges. However inductive loads such as a contractor-coil, heavy- duty transformers, etc. should not be connected across the same supply.2) The voltage sensing circuit is protected by a heavy-duty metal-oxide varistor of 500V rating connected across the load terminals. Hence the load supply should not exceed 500 VAC.3) The current sensing circuit is protected by a replaceable glass-cartridge fuse on the rear of the instrument. This glass cartridge fuse should not be replaced by fuse of higher ratings or wire shorts. Otherwise the instrument may get damaged. 

Over the last 32 years, Delta have supplied virtually thousands of custom-built-equipment. Various industries spanning from caustic soda plants, aluminum plants to electrical equipment mfrs. like switchgear, motor/pumps appliances etc. For switchgear division of L & T, we have fabricated a range of equipment to suit their testing needs. Tailor made DPM's such are these with isolated 0 -10 VAC interface outputs or with band-pass comparator set-point limits have satisfied many different testing needs. Delta's specialty has been the value addition to their standard range of equipment for creation of specific application equipment.
