P2RV-S

P2RV-S Application Field and Working Principle

The P2RV-S electric potential sensor is designed to monitor and measure electrostatic potentials in many areas. It is used for contact-less monitoring of electrical current balance in high-voltage line systems and can measure DC and AC voltages as well. Its standard measuring range is 0 to 2.5 kV.

P2RV-S is used mostly in the protection of substation equipment such as power transformers and related apparatus. It can detect when a dangerous over-voltage has occurred in a station, opening the circuit breaker in order to prevent further damage. It is also applied in the supervisory control and data acquisition systems for the power distribution industry, where it is used to monitor current and voltage signals from multiple points.

The working principle of the P2RV-S electric potential sensor is based on a capacitive voltage divider. The device utilizes the voltage across two precision-machined conducting plates embedded in its body. As the electric potential at the plates varies, so does the capacitance of the plates. This capacitance change is converted into an accessible analog signal by an impedance converter circuit. The generated signal is therefore proportional to the electric potential at the plates.

P2RV-S can also be used in the high voltage laboratories, where it can measure values of up to 4 kV, and is used to measure electric fields in various materials or in the air. It has also found applications in the automotive industry for measuring low-voltage signals which are required for the proper operation of motors and switches.

In conclusion, the P2RV-S electric potential sensor is a powerful and reliable tool for measuring electric potentials in many industries. Its capacitive voltage divider design allows it to accurately measure voltages up to 4 kV while its impedance converter circuit ensures reliable operation and excellent long-term stability.
