Techimp 3 Channel Derivation Box
Techimp Derivation Box allows to connect (permanently or temporarily) a PD measurement instrument to the sensors permanently installed in an electrical asset.
Once installed, it allows the operator to connect the PD System and carry out a PD measurement without any outage of the equipment to be tested.
Features:
- It houses surge arrestors in order to limit the maximum output transient voltage and hence assuring the safety of operators and connected equipment.
- It is housed in a powder varnished thick aluminum box.
- The Derivation Box includes also an output channel for the needed reference voltage signal (synchronization signal).
- In most of the cases, the installation of the Derivation Box installation doesn’t require the outage of the electrical apparatus. The Derivation Box is also provided with a binding post dedicated to the ground connection. Earthing connection must be realized by means of a proper cable, depending on the length and local safety requirement.
- It is also recommended to fix the Derivation Box to a proper support by means of the screws located on the back side of the box. Preferably, the Derivation Box should be wall-mounted. An outdoor version with a protection degree IP65 is available as an option. Higher protection degrees up to IP68 are available as well.
