PPS Clamp Transformer
-
PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.

Partial Discharge
-
Partial discharge (PD) is a local electrical discharge that occurs in imperfections or inhomogeneities. The partial discharge measurement is a so-called “non destructive test” to determine the quality of insulating materials. On the contrary of pure high-voltage test, th test item is not pre-damaged at low PD levels.

Positive Displacement (PD) Meters
-
Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. Positive displacement flow meters are similar in design to the gear pump. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears. A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor, a square wave pulse is produced and a discrete volume of liquid is measured. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow.
