What we do

Green Wood Power

Greenwood Power is one of the leading manufacturers of Voltage Sensors / Current Sensors / Voltage Detectors/ temperature measurement System

Voltage Sensors

Product portfolio includes sensors for gas- & air insulated switch gears in primary- and secondary energy distribution and the list of voltage sensors as follows:
  • Voltage sensor with type C cone, acc. IEC
  • Voltage sensor with shortened cone, acc. IEC
  • Voltage sensor with Nexans Type B cone, acc. IEC
  • Voltage Sensor with type C cone acc. IEC up to 36kV
  • ECO-Voltage sensor with type C cone and correction factors acc. IEC.
  • ECO-Voltage sensor with shortened cone and correction factors acc. IEC

Voltage Detectors

Sensors with a passive capacitive divider inside:
  • Voltage detection sensor with capacitive divider with RJ45 connector, acc. Customer Spec
  • Voltage detection sensor with capacitive divider with type C cone, acc. Customer Spec.

Current sensors

GWP offer a wide range of current sensors. All of them are passive and could be used for first- or retrofit installations, for primary or secondary energy distribution and for medium and low voltage applications.

  • 100A to 400A as a nominal current at an output ratio of 100A//225mV for the „small“ sensor.
  • 300A to 1000A as nominal current at an output ratio of 300A//225mV for the „bigger“ sensor.
The list of sensors as follows :
  • Current sensor for first time installation, acc. IEC.
  • Current sensor for Retrofit, acc. IEC
  • Residual current sensor for Retrofit, acc. IEC.
  • Current sensor for Retrofit, with correction factors acc. IEC.
  • Residual current sensor for Retrofit, with correction factors acc. IEC.
  • Current sensor for Retrofit, with correction factors acc. IEC.

Temperature Measurement System

Newest development of GWP is a temperature measurement system, dedicated for switchgears, for measuring the temperatures either on cables with a wired system or directly on primary busbars with self powered satellite temperature probes communicating with the base station. The station itself provides the values on a Modbus-RTU protocol.

Temperature monitoring system via Modbus

The temperature sensor system is made for solving a big problem in switchgears. This system is modular and can be used in cable compartments of gas insulated switchgears or even in air insulated switchgears, directly on the medium voltage busbars to monitor temperature rises, especially in busbar conjunction points. The system could be delivered wired, for cable application or wireless for busbar installation.
