HOME / Ik Relay Protection - MCF Cable Routing & Structured Cabling
The self-powered protection relay IKI-35 is a protection relay made for distribution applications and due to its design and ease of use best applicable in Ring Main Units and compact substations.
Three KDXG relays are used in conjunction with a ground directional-unit timer relay, and an auxiliary current transformer Type IK for transmission line protection from a single phase-to-ground fault within
The IK protection class is indicated by a digit from IK00 to IK11, the latter represents the highest degree of protection. The higher the number, the more resistant the device is to such impacts.
Original v0 Details Restored for B267 Impact Rating: IK07 vs IK08 vs IK09 vs IK10 - A Comprehensive Guide. Impact ratings, particularly IK ratings, play a pivotal role in determining the
It detects overcurrents and short circuits using split-core CTs on the lines. The IKI-30 offers overcurrent, short circuit, and optional earth fault protection. It is supplied
The IKI-30 is a transformer-powered Protection Relay according to IEC 60255, suitable for... more
The IKI-35 is a compact overcurrent protection relay and is suitable as overload, short-circuit and earth short-circuit protection in combination with circuit breakers or power isolators, as well as overload
Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of
The self-powered protection relay IKI-35 is mainly used for transformer-protection in distribution networks. The use of IKI-35 allows a selective fault isolation during overload and failure situation and
The IK protection class is indicated by a digit from IK00 to IK11, the latter represents the highest degree of protection. The higher the number, the more resistant the
Plus on A1+ With protection diode to protect against wrong polarity and recovery diodes to reduce switching spikes. Plus on A2+ With recovery diodes to reduce switching spikes.
