Ours is the most acknowledged name involved in offering different models of Partial Discharge Meters that includes DTM D, DTM Integrated and DTM Modular. Partial Discharge Meters is used for the measurement of partial discharges in pC and RIV in µV. Partial Discharge Meters feature variable selective filter ranging from 600 kHz to 2400 kHz. And, the alternatively fixed bandwidth wide band filter is from 40 to 220 kHz. These Partial Discharge Meters have built-in oscilloscope to display PD pulses on elliptical time base and window gating facility to mask unwanted noise. Also, these meters have facility to conduct balance mode PD detection to minimize the background noises. All models conform to IEC60270.

High Voltage Transformer is designed to provide a short-time or continuous high ac Voltage. The frequency is normally 50 or 60Hz, but can be higher in special cases. A typical feature is that the excitation of the low voltage winding (excitation winding) is continuously variable up to the required value and right up to the rated voltage of the test transformer. A further feature of a test transformer is that it is able to withstand short-circuit conditions over an arc on a great number of occasions. The time period in which a test transformer is excited is normally short. It often amounts to one minute, sometimes up to 15 minutes.

The oil cooled test transformers manufactured by WSTS in modular design are specified with two output power ratings one for continuous duty and the other for short time duty. Wide range of transformer ratings is available ranging from 100kV, 5kVA to 500kV, 500kVA. Partial discharge levels between <2 pC to 10pC up to rated voltage.

Since the load connected to a test transformer is mostly capacitive, the possibility of compensation with additional reactors, mostly variable, should be considered. Such reactors are important in cascade circuits where they can be installed in the each stage and excited by the coupling windings.

Our Impulse Test Setup is specifically designed to generate impulse voltages, which stimulates lightning strokes and switching surges. Our Impulse Test Setup is available in 140KV, 280KV and 420KV.
