Insulation control systems NPP E'KRA SHE2607 141, SHE2114, etc.

Input insulation control cabinets (KIV) SHE2607 141 (142), SHNE2104 (2114) are designed to control the insulation of 110-750 kV inputs with paper-oil and solid RIP insulation.

Models: SHE2607 141, SHE2607 142, SHE2104, SHE2114.

The insulation resistance monitoring system includes:

• The isolation monitoring terminal is closed.
• Differential current sensors DDT.
• Portable screen devices.

SKI terminals monitor the insulation resistance of the entire network and automatically monitor the insulation resistance of connections on which DDT differential current sensors are permanently installed.

Models: EKRA-207 SKI, EKRA-SKI-M.

RCIE insulation monitoring relays are designed for continuous monitoring of the insulation resistance level of the poles of the DC network relative to the "ground".

Models: RCIE-00X, RCIE-20X.

A portable device for searching for earth-locked feeders in an operational DC network is used in conjunction with all relays and isolation monitoring terminals.

The complete portable insulation resistance monitoring device UKP EKRA-KSI is used for temporary connection and periodic verification of the insulation resistance level of the DC network at power facilities and industrial enterprises without permanently installed insulation monitoring systems.

The SCP SKI verification device is designed to test insulation monitoring devices from various manufacturers in 220 V DC networks before they are put into operation.

The AP relay adapter is designed to convert the voltage of the controlled network supplied to the measuring inputs of the RCIE relay or the EKRA-SKI, EKRA 207 SKI and EKRA-SKI-M terminals to the required values.

Models: AR-1, AR-2.
