The WIP1-1 is a versatile, self-powered time overcurrent relay with selectable multi-characteristics. It supports both definite time and inverse time tripping characteristics. Designed for applications without built-in batteries, this relay draws power from current transformers (CTs) and provides the necessary tripping pulse energy to the circuit breaker.
Key Features
Self-Powered Operation:
The WIP1-1 does not require an auxiliary voltage supply. It operates using energy derived from the CT circuits.
It delivers tripping pulse energy directly to the circuit breaker, making it suitable for switchboards without built-in batteries.
Wide Setting Ranges:
The relay’s broad setting ranges accommodate a variety of equipment, ensuring effective protection across different applications.
Optional Features:
Earth Fault Element (Option IE): For detecting ground faults.
Negative Sequence Element (Option IS): For monitoring unbalanced load conditions.
Battery Backup:
The relay includes a battery for powering the LC display and for fault value memory and relay reset functions.
The battery life exceeds 10 years and failure of the battery does not impact the relay's protective functions.
Operating Characteristics
Transformer Current Mode:
The WIP1-1 operates without additional auxiliary voltage supply by using current transformers.
Tripping starts at the following current values:
1-phase: approximately 0.35 A
2-phase: approximately 0.22 A
