Remote Isolation Options
Single Phase TRANSIG
The 9699 model is a rail-mounted current transformer with two terminals for the transformer secondary and ground lugs for the chassis ground. The wiring connections for the transformer's secondary outputs are to compression-type terminal blocks. The Transig units are needed when incorporating the DFR Low Current Analog Input Isolation modules.
3-Phase TRANSIG
The 9701 model is a plate-mounted 3-phase current transformer with six terminals for the secondary transformer and a ground lug for the chassis ground. The wiring connections for the transformer secondary outputs are to compression-type terminal blocks. The Transig units are needed when incorporating the DFR Low Current Analog Input Isolation modules.
Remote Isolation Module with or without Test Switches
Mehta Tech also can supply several versions of self-contained cabinet-mounted isolation modules installed into any standard 19" (24" w/adapter) equipment cabinet. The standard configuration is 4RU in height, and all wiring connections are barrier-type terminal blocks.
Split Core CT
The Split-Core Current Transformer interfaces with the analog isolation devices. It is designed for indoor use only and as an auxiliary CT, and breaking the CT circuit is not necessary when deploying the Split-Core CT.
