TUNABLE RESONATING INDUCTER
The tunable resonating inductor is an essential accessory used in conjunction with Capacitance and Tan-Delta test sets to expand the capacitance range of the test sets .The tunable resonating inductor is connected in parallel with the internal power supply of the test set and the test object. Tuning the resonating inductor varies the inductance to tune the parallel circuit for minimum resistive load current to be taken from the source, while a majority of inductive current negates the capacitive current requirement of the test object.The tunable resonating inductor is epoxy molded to avoid effect of atmospheric conditions on the insulation capacity of the coil. The body comprises of a welded steel frame with thick Aluminum panels designed to keep the weight low but withstand the rigors of field operation. TRI series can also be connected to Hipot HV units, in similar configurations, with necessary changes in a few connections so as to be able to reflect correctly on the current measuring modules and overcurrent protection on the main units. FEATURES - For use along with Capacitance & Tan-Delta test sets & Hipot test sets to expand range of measurements for large capacitance objects like Rotating Machines (Generators & Motors) and XLPE HV Cables- Reduces HV Power Source capacity needs by almost 90%- Eliminates need for multiple fixed reactors in parallel and need for know-how of approximate capacitance before testing. Provides optimum power balance- Designed to be compact and light-weight to be transported for field testing- Dual-spindle gear mechanism with auto-balancers for variation mechanism ensures smooth operation through-out its usable life- Available in voltage variants of 12kV, 15kV and 30kV- Available for compensating Capacitances from 0.05uF to 3uF- Indicator level indicates position of variable arm, and also approximate capacitance- HV-shielded cables and connectors, for safe operation.- Large heavy duty rubber lined wheels for noise-less movement thro shopfloor. Locking arrangement also provided. APPLICATION Capacitance and dissipation factor “power factor” testing is used to determine the quality of electrical insulation. Hipot testing is done at higher than service level voltages to ensure that insulation can withstand service level conditions for a longer period of time without significant deterioration. The insulation characteristics may degrade during usage due to temperature variations, contamination, moisture ingress, partial discharge or normal aging. Tan-Delta measurements are used to detect these problems before complete insulation breakdown occurs. It is necessary to perform periodic Power Factor checks on insulation of all types of HV/EHV equipment in service, or those which are intended to be put in service. While the C&DF test sets available in the market can typically cater to the power sourcing requirement (< 3kVA) that will be demanded by certain test objects like Transformers, Bushings, CTs, PTs, etc, there are certain high-capacitance objects like large Motors, Generators, Cables that typically have capacitance levels ranging from 0.05uF to 1uF or some typically long cable runs even having up to 3uF!

Resistivity Tester
PE-AORDF-1 Fully Automatic Oil Resistivity & Tan-delta tester is a 2-pc unit, consisting of Heater unit and Measuring Bridge. The Stainless Steel oil cell is to be mounted inside the Heater unit. Measuring Bridge consists of AC/DC high voltage supply, Tera-ohm meter, and precision electronic bridges to measure & derive the readings forResistanceResistivityCapacitancePower FactorTan-deltaWatt-lossDielectric ConstantTemperature Oil suffers from electrical and mechanical stresses while a transformer is in operation. In addition there are contaminations caused due to chemical interactions with windings and other solid insulations, catalyzed by high operating temperature. As a result the original chemical properties of Transformer Oil changes gradually, rendering it ineffective for its intended purpose after many years. Hence this oil has to be periodically tested to ascertain its basic electrical properties, and make sure it is suitable for further use, or necessary filtration/regeneration has to be done. Testing of DC resistivity and Tan-delta/Dissipation-Factor of such insulating Oils is one of the most critical tests to determine the Oil condition. Power Electronical provides instruments to achieve this objective of accurately measuring the Power-Factor and Volume Resistivity of Insulating liquidsPre-programmed international test methods compliant toASTM-D924-04 l ASTM-D1169 l VDE-0380-2 l IEC-60247 l IEC-61620 l BS-5737 FEATURES - Complete automatic test procedure.
