Kilo Volt Meter (kV) meters used tomeasure the kilo volt value of an Instrument Transformer, CT/PT etc. The unit is used for higher value calibration with a wide range from 1% to 110%. Kilo Voltmeters are highly accurate, portable voltage measurement systems traceable to NABL standards. The Kilo meter series consists of a high voltage divider assembly, a precision readout device and interconnection leads. The battery operation makes the system completely portable for field testing while the precision divider assembly and readout device makes it suitable for laboratory use.
Inductive Load Test Set
Load Banks are designed for load test to be carried on Single/Three Phase AC/ DC Power Supplies, DG sets, UPS and Inverters etc. We manufacture loads up to 3000kW suitable for working on Single Phase 230V +5% and 3Phase 400 V +5% 50HzAC supply. The power factor in AC can be variable/adjustable from 0.2 lag to unity to 0.3 lead. The capacities are available from 5kW to 3000kW. The units are available with Stepped & Stepless versions with Manual, Semi Automatic and Fully Automatic Controllers. Digital Multi function meters are also available to indicate voltage, current, watt, KVAr, Pf.

- Capacitive Loads.
- Resistive/Inductive combined Loads.
- Resistive/Inductive/Capacitive combined Loads.
Each load banks consist of coarse and fine controls as per the specific requirements.
Variable Auto Transformers
‘RE’ VARITX is the trade name of the continuously variable voltage Auto transformer manufactured by ‘RE’. It is an most economical effective device for step less and continuous voltage control of Single Phase and 3 phase AC voltages for numerous applications for the industrial and Laboratories usages for testing and calibration purposes. ‘RE’ VARITX are used for operation at nominal voltage of 240V AC to give output Voltages between 0 to 270V at 50/60 Hz by a Booster Auto Transformer. Three such ‘RE’ VARITX connected electrically in star and mechanically interlocked to move together are used for operation on 415 Volts, 3 phase AC supply to give output from voltage from 0 to 470 Volt at 50/60Hz. ‘RE’ Manufactured VARITX is having good Regulation with Negligible waveform distortion. Varitx are robust, energy efficient, noiseless and easy to operate with excellent short time over load capabilities. ‘RE’ manufacturers specialized Oil cooled or air cooled motorized/manually operated VARITX upto 800 Amps with supply voltage of 240 Volts to give output voltages from 0 to 350 Volts, 3 Phase VARITX up to 800Amps with input supply voltage of 415 Volt 3 Phase to give output Voltages from 0 to 600V.
Tracking Resistance Erosion Test Equipment is used for checking the relative behavior of solid electrical insulating material with regard to their susceptibility to surface tracking when exposed under electric stresses, to water and contaminants, from the surroundings.
The grading of materials arrived at by checking the tracking index may possibly differ from that obtained by utilizing other checking methods for the measurements of the tracking index.
The results obtained by checking tracking index are not used directly for evaluation of safe creepage distances while designing any electrical apparatus.
With this apparatus drops of an electrolyte are dropped at defined time interval to the surface of insulating materials between two electrodes to which a voltage is applied.
The number of drops at which break down occurs across the surface is the function of voltage
The numerical values of the voltage corresponding to the asymptotes defines the tracking resistance.The value of voltage corresponding to number of drops is taken as the comparative index. (This test should be done as fast as possible)
The number of drops to cause tracking at value of predetermined test voltage 10% below the number of drops value is indicated as the degree to which the reported comparative tracking
