Sweep Frequency Response Analysis (SFRA) is a powerful and sensitive method to evaluate the mechanical integrity of core, windings and clamping structures within power transformers by measuring their electrical transfer functions over a wide frequency range. SFRA is a proven method for frequency measurements.

INSER HITECH ENGINEERS aims to provide testing and commissioning, preventative maintenance of all projects related to Infrastructures, Industries, and Power Plants etc new and existing plants in a cost effective manner. We have the resources and personnel to carry out the following either on site or in house; HV & LV Switchboards EHV Switchyards Secondary Injection of Protection Relays Calibration of Transducers Primary Injection of Current Transformers Insulation Resistance Tests Control & Relay panel wiring, modification & Retrofit Earth Testing Contact Resistance Testing of High Voltage Equipment Transformer Winding Resistance Testing Cable and Cable Fault Locating Polarization Index Tests Power Transformer Testing

Electrical tests on transformers, current transformers, voltage transformers, grounding systems, lines and cables, and circuit breakers can be performed with the CPC 100. The CPC 100 is the base for multiple accessories. These facilitate further applications, such as tan delta measurements, as well as line and ground impedance measurements. The patented test system replaces several individual testing devices and offers new, innovative testing methods.

The protection functions of the relay and the transient currents and voltages are still the same, but it is the present state of technology that offers new possibilities and makes the number of functions in the relay more complex. It is generally agreed that testing numerical protection should be different from older techniques. Some basic aspects of numerical protections generally address this.

Universal Circuit Breaker Operational Analyser to test all types of CBs - LV, HV, EHV & UHV. Quick performance check of CB by measuring C, O, C-O, O-C & O-C-O timings. Dynamic Contact Resistance Measurement for condition monitoring of the contacts without opening the interrupter. Analysis of Travel Characteristic with customized Travel Transducer cum Fixtures. Saves down time & number of operations of CB by testing all the critical performance parameters of all the poles breaks in a single shot. Healthiness of Auxiliary contact by measurement of Auxiliary contacts timings. Healthiness of Close Trip coils of all three poles monitored simultaneously.
