Bushing Monitoring

DM Series

DM Series monitors provide advanced partial discharge and bushing monitoring for transformers. The DM Series product is scalable allowing customers to extend the coverage of monitoring to suit applications today and tomorrow. DNP and Modbus communication protocols supported.

iBridge

IBridge Networking and Communication Solution

Installing data connections in a substation can be expensive and time consuming. The Dynamic Ratings iBridge product saves time and money while avoiding the security concerns associated with wireless antenna systems. The iBridge inductively couples the data onto existing conductors, providing the ability to send serial and ethernet based data utilizing hardware that can be installed in just a few
minutes.

The iBridge Networking and Communications Solution delivers data seamlessly from IEDs (Intelligent Electronic Devices), RTUs and cameras with continuous reliability. Networks can be configured as point-to-point or multidrop configurations. 128-bit encryption provides enhanced security. Existing AC or DC wires can be used, which eliminates the cost of trenching, permits and additional cables. Schematics often need no modifications. The iBridge reduces project installation time and cost, helping project managers complete projects on time and on budget.

Rotating Machine Monitor (RMM)

The RMM provides information as to the health of the stator winding insulation in medium and high voltage motors and generators and can be used on variable frequency drives (VFD). Communications ports include Ethernet, USB and RS-485 with a standard communication protocol using ModBus. DNP-3 is available upon request.

SCM

Switchgear and Cable Monitor (SCM)

The SCM Partial Discharge Monitoring System can have up to 60 channels, which makes it a cost effective solution for monitoring large line-ups of switchgear and cable systems. Continuous, on-line monitoring of PD activity, provides the means to detect pending insulation failures that are not present in traditional maintenance practices.

High Voltage

Circuit Breaker and SF6 Gas Monitoring

Dynamic Ratings offers On-Line Circuit Breaker Performance and SF6 Gas Density Monitors. These on-line circuit breaker monitors are ideally suited for implementing predictive maintenance, maintenance deferral, condition based maintenance and increase environmental protection from SF6 gas leaks. These intelligent electronic devices (IED) monitor the condition of the main contacts, mechanism and dielectric; and logs the following information during CB operation:

  • Trip Time (mS) (also known as Opening Time)
  • Arc duration (mS) (phase segregated)
  • Clearing Time (mS) (also known as Interrupting Time)
  • Cumulative I2 x T or I x T on the main contacts (phase segregated) from arcing
  • Restrike Occurrence (phase segregated)
  • Mechanism opening travel time (mS)
  • Mechanism closing travel time (mS)
  • Operation Counts
Battery Monitoring

Stationary Battery Monitoring

Monitoring of stationary battery systems has increased in importance due to the decline of craft specialists, reductions of maintenance personnel and the increasing number of unmanned facilities.

Additionally, NERC PRC-005 requires electric utilities to implement maintenance plans for protection systems associated with the Bulk Electric System.

These devices meet NERC PRC-005 monitoring requirements by monitoring, logging and alarming on the following information:

  • DC supply voltage
  • Battery float voltage
  • Battery float current
  • String continuity
  • Intercell connection integrity
  • Cell ohmic values relative to baseline values
  • Unintentional grounds
  • Electrolyte levels (optional)
