POWER ELECTRONICAL&rsquo;s Manual Capacitance and Tan-Delta Test System (Model HVTD-12/100) has inbuilt HV Power Source, Standard Capacitor (SF6 Gas Filled), and set of cables. The compact design of the system uses the principle of three winding differential transformer on a high permeability mu-metal core to measure the Capacitance of the object and its Tan-Delta value accurately. The Capacitance &amp; Dissipation Factor (Tan-Delta) Test System is contained in a sturdy metallic housing with mu-metal lining which shields it from external electromagnetic &amp; electrostatic influences. Built-in battery powered Null indicator makes the system suitable for operation in workshop, factories, High Voltage Switch Yards etc. It is suitable for both grounded as well as ungrounded objects. The system is provided with High Voltage Protection Devices which protect the system and operator against failure of test object or standard capacitor. FEATURES: - 12kV 100mA - Tan-Delta accuracy of 1 X 10 -4&nbsp; - Low Dissipation factor Reference Standard Capacitor of 1 X 10E-5&nbsp; - UST, GST and GSTg testing modes - Open Ground Indication&nbsp; - HT Cut- off on overload.&nbsp; - All operating controls are at earth potential APPLICATION - Transformer testing&nbsp; - Testing Bushings, CTs, PTs, etc at substations - Testing Rotating machines (LV Motors/Generators) on-site

TD GUARD intelligent PD sensorUltimate solution for transformer monitoring TD Guard Intelligent Sensor is an on-line CONTINUOUS Capacitance and tan-&delta; monitoring system for transformer bushings. TD Guard Intelligent Sensor is the first and only instrument on the market providing absolute Tan-&delta; measurement in on-line permanent monitoring of transformer bushings, granting the best level of diagnostic leverage and reliability. Sensitivity better than 10-4. Benefits <ul><li>First instrument on the market measuring absolute Tan-&delta; values in on-line permanent monitoring</li><li>Innovative instrument for Capacitance, Tan-&delta; and &Delta;tan-&delta; recording, storage & processing</li><li>Zero drifts, innovative design for high thermal stability levels without drifts</li><li>Fast response and accuracy</li></ul>&nbsp; Characteristics TD Guard Intelligent Sensor consists of a microprocessor-controlled unit supporting sophisticated sensors and conditioning front end. Fiber optic interfaces allow data download by a standard PC or a server able to record values of &Delta;tan-&delta; (relative measure) and Capacitance and threshold setting.TD Guard has the capability to present two alarm levels, according to a traffic-light approach, using the dedicated LED front lights or activating external alarms media by dry contact interface. False alarms are avoided through advanced signal processing and field-proven algorithms able to eliminate the effect of noise or other environmental conditions that could lead to wrong diagnosis and inappropriate corrective actions.TD Guard implements transformer bushing&rsquo;s on-line monitoring through Capacitance and relative &Delta;tan-&delta; measurement. Smart sensing algorithms are applied to obtain fast response and accuracy.&nbsp;This intelligent sensor is designed to be used with TECHIMP PD analyzer, as the PDCheck unit and Techimp DGA-IS, providing Global diagnostic coverage and, thus, superior failure prevention. It may also be used as a stand alone device to get basic alarms on programmable threshold levels.
