Every electrical apparatus or machine Is provided with insulation between live part and earth or between two different sections of live parts. This insulation is required to be tested at high voltage values recommended by applicable relevant standards.
The standard Specification for various electrical apparatus specifies Power Frequency Voltage withstand test at different levels depending upon working voltage of electrical apparatus. It is observed from the various standards for electrical equipments that the minimum power frequency voltage withstand test level for electrical insulation is 2kV for one minute.
We have, therefore, standardized on manufacture of’AE’ High Voltage Breakdown Testers with rated voltage of 5kV.
High Voltage Tests Sets of higher voltage upto 600kV are also manufactured against specific requirement. The standard voltages are 10kV, 15kV, 20kV, 25kV, 30kV, 50kV, 100kV, 150kV, 200kV & 300kV. The test sets uplo 30kV are manufactured in Air Cooled design while the sets of 50kV & above are manufactured in Oil Cooled design. The output of these high voltage testers is single phase 50/60Hz. The standard H.T. current rating of air-cooled design as also of oil cooled design upto 150kV is 100mA for 30 minutes. For voltages ranges above ‘AE’ make 5kV A.C. (with 2.5kV tap) High Voltage Breakdown Tester is portable, sturdy & plug in to start type construction & requires minium table space. It broadly consists of 3 main sections.
High Voltage Transformer : The High voltage transformer is single phase, single pole type & is of double wound resin moulded construction. The H.T. winding is provided with graded insulation such that one end is insulated for 2kV insulation and is earthed through a current sensing transformer & miiliammeter whereas other end isinsulated for full rated voltage & the same brought out through H.T. Cable & spring loaded Prod.
Variable Voltage Source : Variable Voltage supply is provided through a Dimmerslat (Variable auto-transformer) havingasuitable rating corresponding to the rating of H.V. Transformer. Dimmerstat Is rated for 230Volts A.C. input & 0-270V output. Limit switch at zero position end of Dimmerstat winding is provided to facilitate the H.T. winding to.

We have separated our infrastructural facility into several units and one of them in warehouse. In order to maintain high quality standards, we laced our facility with modern technology. The transactions related to payment carried out between us and our clients are kept confidential. You details are not shared with anyone except the concerned personnel to ensure high level of security.
The EMS type AC voltage stabilizer basically comprises of the following –
The PMT-9 Multifunction Programmable Transducer measures the several variables of an electric power system and processes them to produce 4 analog output signals. 2 digital output signals are available for signaling the limits. The limits of the outputs can be set by individual measurand or logically combine up to three measurand. The principle of measuring is Dedicated DSP Controller for best calculation of RMS values and Power.
The PMT-9 is equipped with USB serial port interface through which using the corresponding software one can connect, program, or access and execute useful ancillary functions. The ancillary functions include a power system check, provision for displaying the measured variably on a PC monitor, the simulation of the outputs for test purposes.
The PMT-9 is also equipped with a RS 485 bus interface (MODBUS®). The RS 485 interface enables the user to determine the number of variables to be supervised (up to the maximum available). The levels of all internal power/ energy meters that have been configured can also be viewed. Provision is made for programming the PMT-9 via the bus. A standard EIA 485 interface can be used, but there is no dummy.
Features : Simultaneous measurement of several variables of a heavy-current power system / Full supervision of an asymmetrically loaded four wire power system, rated current 1 to 6 A, rated voltage 57 to 400V (phase-to-n€ utral) or 100 to 693 V (phase-to-phase)For all heavy-current power system variables.
We make us of only experts' certified packaging material to meet the personalized and standard packaging requirements of the clients. Rest assured us for the packaging of the products. Engaged in the trade of supplying the excellent product range, we are efficiently operating from Mumbai(India).
Features :
We are a quality-driven firm and make sure that our offerings are properly kept and processed. For this, we have installed all the in-house storage facility that helps us in meeting bulk and urgent requirements of the clients. Purchasers can place wholesale or retail orders with any time of the year and expect timely arrival of deliveries.
Application: Protective devices such as over current relay, short circuit relay, circuit breakers and CTs etc must be checked and calibrated regularly to ensure that they are always ready to operate correctly. Current injection testing sets will help detecting faulty or incorrectly adjusted protection circuit / device and thereby avoid damage to the system. With the help of current injection test sets the correct functioning of protective device / circuit is ensured. The units are available in single phase version for small capacity and single or two phase version for higher capacities.
Features
Purchasers can place wholesale or retail orders with any time of the year and expect timely arrival of deliveries. We have installed a large storage facility wherein we keep a large stock of the offerings. This facility helps us in keeping the entire lot away from the damaging factors like moisture, sunlight, dust, rain, etc.
