TD Guard Intelligent Sensor is an on-line CONTINUOUS Capacitance and tan-δ monitoring system for transformer bushings. TD Guard Intelligent Sensor is the first and only instrument on the market providing absolute Tan-δ measurement in on-line permanent monitoring of transformer bushings, granting the best level of diagnostic leverage and reliability. Sensitivity better than 10-4.

• First instrument on the market measuring absolute Tan-δ values in on-line permanent monitoring
• Innovative instrument for Capacitance, Tan-δ and Δtan-δ recording, storage & processing
• Zero drifts, innovative design for high thermal stability levels without drifts
• Fast response and accuracy

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 Δtan-δ (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’s on-line monitoring through Capacitance and relative Δtan-δ measurement. Smart sensing algorithms are applied to obtain fast response and accuracy.

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.

This testing system is designed to perform Tan Delta and capacitance measurement on CTs, VTs, Power Transformer and CB.

• Fully automatic
• Variable output frequency: 15 - 500 Hz
• Power dissipation factor test with the module TD 5000 ( voltage up to 12 kV)
• PADS - Power Apparatus Diagnostic Software for automatic testing, assessment and report
• USB interface and Ethernet interface for PC connection
• Compact and lightweight.

SFRA 5000 is a standalone sweep frequency response analyzer for the high accuracy transformer analysis and integrates the STS and TD 5000 family test sets. The SFRA 5000 offers both high precision and portability in a single package, providing all the accessories required for fast, easy to use, reliable and repeatable measurements. Without the need for a PC to compare transformer fingerprints, the SFRA 5000 decreases test time enabling the engineer to complete testing in a much shorter period of time than previously possible. SFRA 5000 is provided with its own embedded software, giving the possibility to the engineer to zoom into a portion of the sweep in order to inspect any differences in the plot in more detail during or after a sweep. This enables diagnosis of transformer faults early on in a transformer sweep, without the need for a PC.
